When you plug a cable into your EV, at least four separate international standards are quietly working together to keep you safe. They govern the shape of the pins, the current the cable can carry, how well it resists rain and dust, and what happens if something goes wrong inside your home’s wiring. We’ve mapped every relevant standard so you know exactly what to look for: IEC 62196-2, IEC 62752, IEC 61851-1, BS 7671:2018+A2:2022 Section 722 and the IET Code of Practice for EV Charging Equipment Installation, 5th edition.
The five standards that govern your EV charging cable
Understanding these standards in isolation is useful. Understanding how they fit together, and which layer of your charging system each one covers, is genuinely useful. Think of them as five concentric rings of protection around every charge session.
- Layer 1 (Connector): IEC 62196-2 | Pin geometry, current rating, mechanical tests | Applies to: Type 1 & Type 2 connectors
- Layer 2 (Mode 2 cable): IEC 62752 | In-cable control & protection device (IC-CPD) | Applies to: Granny / 3-pin cables only | Current limit: 10A / ~2.3kW
- Layer 3 (Charging mode): IEC 61851-1 | Defines Mode 1, 2, 3, 4 | Mode 3 = wallbox AC charging (UK standard)
- Layer 4 (Home circuit): BS 7671:2018+A2:2022 Section 722 | DC-fault protection, RCD type, dedicated circuit | Requires: Type B RCD or Type A + 6mA DC device
- Layer 5 (Installer): IET Code of Practice 5th ed (2023) | Installer obligations, fire safety, commissioning
IEC 62196-2: connector geometry and pin ratings
IEC 62196-2 is the standard that defines the physical connector itself. It specifies pin geometry, pin spacing, current ratings, voltage ratings, contact resistance, temperature rise limits under sustained load, and mechanical endurance (the number of plug-and-unplug cycles the connector must survive). Every Type 2 connector sold in the UK must comply with IEC 62196-2, the standard that establishes Type 2 (Mennekes) as the mandatory AC charging connector for electric vehicles sold in Europe and the UK since around 2018.
When you see a Type 2 plug on an EV cable, IEC 62196-2 is what defines the seven-pin layout: three phase conductors, a neutral, a protective earth, a control pilot (CP) and a proximity pilot (PP). The CP pin is what allows the car and charger to complete their digital handshake before any current flows. A cable without genuine IEC 62196-2 conformity may have the right physical shape but fail the current-rating or contact-resistance tests that matter most under charging load.
IEC 62752: the in-cable safety box (Mode 2 / granny cables)
If your cable has a 13A domestic plug on one end and a brick-shaped control unit somewhere along its length, it is a Mode 2 cable, and IEC 62752 is the standard that governs that control unit. The formal name for the box is an In-Cable Control and Protection Device (IC-CPD).
IEC 62752 requires the IC-CPD to limit charging current to 10A on a UK 13A domestic socket. That is approximately 2.3kW, or around 8 miles of range per hour. Non-compliant marketplace cables that allow 13A draw on a 13A socket bypass this protection. A standard ring-main socket and its associated wiring is rated for continuous 13A load, but 13A is exactly the rating, not a safe working margin, and the standard was designed to prevent sustained 13A draw through wiring that may already be loaded by other circuits on the ring.
IEC 62752 also requires the IC-CPD to monitor earth continuity and cut power if a fault is detected. This is one of the key reasons we only source Mode 2 cables with demonstrated IEC 62752 compliance, and why we recommend treating any cheap Mode 2 granny charger from an open marketplace with considerable caution.
IEC 61851-1 defines charging modes 1-4
IEC 61851-1 is the framework standard that defines what the four EV charging modes actually are. In brief: Mode 1 is direct connection to a domestic socket with no additional control (not permitted in the UK or most of Europe); Mode 2 is the granny/IC-CPD cable approach; Mode 3 is the standard AC wallbox or public charging post approach using the control pilot signal; and Mode 4 is DC rapid charging via a dedicated charger (CCS, CHAdeMO).
When a cable is described as “Mode 3”, which applies to every standard Type 2 to Type 2 cable used with a wallbox, this references IEC 61851-1. The standard defines the pilot signal voltages and duty cycles that the cable and vehicle use to negotiate the maximum current, confirm earth continuity, and authorise charging to begin. A cable cannot be “Mode 3 compliant” without a connector that meets IEC 62196-2. The two standards work together.
Your home circuit protection under BS 7671:2018+A2:2022 Section 722
BS 7671:2018+A2:2022 is the IET Wiring Regulations, the primary electrical installation standard in the UK. Section 722 covers EV charging specifically. It mandates that every EV charging circuit must have:
- A dedicated circuit: an EV socket on a shared circuit alongside other loads is not compliant.
- DC-fault protection: either a Type B RCD (which detects smooth DC faults of 6mA or above) or a Type A RCD combined with a separate 6mA DC-fault detection device. A standard Type A 30mA RCD alone is not sufficient.
The reason for the Type B RCD requirement is specific to EV chargers. Some charger designs produce a smooth DC component as a by-product of their internal electronics. This DC component can “blind” a conventional Type A RCD. The RCD no longer trips reliably on an AC fault because the DC saturates its sensing core. A Type B RCD detects both AC and DC fault currents. For more on this, see our detailed guide to Type B RCD for EV charging.
IET Code of Practice for EV Charging Equipment Installation, 5th edition: installer guidance
The IET Code of Practice for EV Charging Equipment Installation, 5th edition (2023) is not a product standard. It is guidance for the person installing your home wallbox or socket. It covers: how to assess an existing installation for suitability, fire-safety considerations (particularly in garages and car parks), earthing and bonding arrangements, PEN-fault protection requirements for TN-C-S (PME) supplies, and commissioning and testing procedures.
This is the document a competent electrician references when they install your EV charging point. Its existence matters to you as a cable buyer because it means the installation your cable connects to should also have been done to a documented standard, not just a guesswork socket on an existing ring main.
What CE and UKCA marking actually tells you
Both marks tell you the manufacturer has declared that the product conforms to the relevant regulations. Neither mark is a government stamp. They are manufacturer declarations. The difference is jurisdiction: CE covers the EU and remains valid in Great Britain during a transition period; UKCA (UK Conformity Assessed) is the post-Brexit marking for the GB market, required under the Electrical Equipment (Safety) Regulations 2016.
For an EV charging cable, the relevant regulations require conformity with IEC 62196-2 and IEC 61851-1. For a Mode 2 granny cable, IEC 62752 is also required. The mark tells you the manufacturer has declared this conformity and, where required, had the design assessed by a Notified Body.
What the mark does not do is guarantee genuineness. It is possible, and unfortunately common on open marketplaces, to print a CE mark on packaging without having conducted any of the required testing. The mark printed on a counterfeit cable looks identical to the mark on a certified cable. This is why the mark alone is not sufficient; you also need to verify it against the checks in the next section.
How to spot a non-compliant cable
The most reliable indicator of a non-compliant cable is not the presence of a mark. It is the absence of supporting documentation. A genuinely certified cable comes with a product data sheet or declaration of conformity that names the standards it has been tested against. A counterfeited cable does not.
- Check | Genuine cable | Red flag
- CE / UKCA mark | Present, correct size (min 5mm), correct font | Absent, blurry, wrong proportions
- Manufacturer name + address | Printed on cable or plug body | Missing or only a website URL
- Current rating | 16A or 32A moulded/printed on plug | No rating visible
- Voltage rating | 250V (single) or 400V (3-phase) printed | Missing
- Standard reference | IEC 62196-2 and/or IEC 61851-1 on spec sheet | No standard cited
- Conductor marking | Cross-section (e.g. 2.5mm² or 6mm²) on cable | No cross-section mark
- IP rating | IP55 minimum stated | No IP rating stated
Six red flags worth knowing: no CE or UKCA mark, or a mark that is printed at the wrong size or in the wrong weight of font; no manufacturer name and postal address on the cable body or packaging; no current rating (16A or 32A) printed or moulded onto the plug or cable; a price significantly below specialist retailers; a sheath that feels brittle or stiff at room temperature (quality TPU and TPE sheaths feel flexible); and no printed IP rating. See our full guide to IP protection rating in detail for what to look for there.
Why marketplace cables are a risk
Open marketplaces (Amazon, eBay, Wish and their equivalents) do not independently verify the claims made in product listings. A cable listed as “IEC 62196-2 certified” on an online marketplace may have been tested by no one, or tested once to a lower standard and then sold as meeting the full certification. This is not a theoretical risk: it is a documented pattern across electrical products.
The specific risk with a non-compliant EV cable is sustained overcurrent. A cable with undersized conductors (say, 2.5mm² where 6mm² is needed for 32A) will run hot under charging load. The outer jacket may feel warm well before the temperature reaches a point where thermal protection, if it exists, activates. Over weeks and months, this degrades the insulation. The IET Code of Practice for EV Charging Equipment Installation, 5th edition (2023) is clear that the quality of the cable is part of the installation’s overall safety, not an afterthought.
A cable purchased from a UK specialist retailer (one with verifiable company registration, a physical address and a warranty they actually honour) carries a different level of accountability than an anonymous listing.
How we quality-check every cable before it ships
We do not manufacture cables ourselves, which means our leverage is in supplier selection and incoming quality checks. Every supplier we work with must provide a Declaration of Conformity referencing IEC 62196-2 and the relevant mode standard, UKCA/CE documentation with a Notified Body reference where required, and sample test reports showing conductor cross-section, contact resistance and temperature rise under sustained load.
In our own returns data, the most common reason a customer contacts us about their cable is not a manufacturing fault but a lost cable. That tells us something qualitative about the durability of the cables we choose to stock. We do not publish precise returns figures because we think self-reported numbers are easy to manipulate; what we can say is that our warranty claim rate is, in our experience, low relative to volume sold, and that the claims we do see are handled promptly.
Frequently asked questions
What standards must an EV charging cable meet in the UK?
A UK EV charging cable must comply with IEC 62196-2 (connector design, pin ratings, mechanical endurance), IEC 61851-1 (the charging mode framework, which puts wallbox use in Mode 3), and, for Mode 2 granny cables specifically, IEC 62752 (in-cable control and protection device). The home electrical circuit it connects to must comply with BS 7671:2018+A2:2022 Section 722, and any installer must follow the IET Code of Practice for EV Charging Equipment Installation, 5th edition (2023).
What is the difference between CE and UKCA marking on an EV cable?
CE marking shows conformity with EU directives and remains valid in Great Britain for most products during an ongoing transition period. UKCA (UK Conformity Assessed) is the equivalent marking for the Great Britain market post-Brexit, declared under the Electrical Equipment (Safety) Regulations 2016. Both can appear on cables sold in the UK today. The critical point is that the underlying testing behind either mark must be genuine. A CE or UKCA mark printed without real conformity testing behind it is fraudulent, and this does occur on open marketplaces.
Are cheap EV cables from Amazon or eBay safe?
Not reliably. Counterfeit and untested cables do circulate on open marketplaces. It is worth checking the warning signs listed in this article before you use any cable purchased on a marketplace: missing or incorrectly formatted CE/UKCA marks, no manufacturer address, no printed current rating, prices significantly below specialist retailers. A cable that does not genuinely meet IEC 62196-2 may fail mechanically or thermally under sustained charging load.
How do I check if my EV cable is compliant?
Look for: a CE or UKCA mark of the correct size and font; the manufacturer’s name and UK or EU address printed on the cable or plug; a current rating (16A or 32A) moulded or printed on the plug; and a product data sheet citing IEC 62196-2 and IEC 61851-1. Reputable specialist retailers provide this documentation on request or published on their product pages.
Why does a granny charger need its own standard?
Because a Mode 2 cable plugs into an ordinary domestic socket that was never designed for sustained high-current draw over many hours. IEC 62752 specifies the in-cable control and protection device that limits current to 10A, monitors earth continuity and cuts power if a fault is detected. Without genuine IEC 62752 compliance, the control box may fail to detect a fault or, in the worst case, allow the full 13A draw on a socket that cannot safely sustain it.
Does my home circuit need anything special for EV charging?
Yes. BS 7671:2018+A2:2022 Section 722 requires a dedicated EV circuit with DC-fault protection: either a Type B RCD or a Type A RCD combined with a separate 6mA DC-fault detection device. A standard Type A 30mA RCD is not sufficient because EV chargers can produce a smooth DC component that can saturate a Type A device and prevent it from tripping on a genuine fault.
Do I need to have my EV cable inspected periodically?
The cable itself does not require periodic certification, but the IET Code of Practice for EV Charging Equipment Installation, 5th edition (2023) recommends that the fixed installation (socket or wallbox and its dedicated circuit) be inspected at the interval recommended by the installer, typically every five years or on change of occupancy. For the portable cable, a monthly visual check of the jacket, strain relief and pins is good practice; see our guide to how to look after your EV cable for the full routine.
