In practice, the assessment almost always concludes that Type 2 surge protection is needed — modern EV charger electronics are vulnerable to transient overvoltages from lightning and grid switching. It is strongly recommended for most installs and is already included if you select that option.\u003c\/div\u003e\n \u003c\/details\u003e\n\n \u003cdetails\u003e\n \u003csummary\u003eWhen would I need a kWh meter?\u003c\/summary\u003e\n \u003cdiv class=\"faq-body\"\u003eA kWh meter records how much electricity the EV charger has consumed. Common uses include: rental properties where the landlord wants to recover the cost of electricity from tenants; workplace charging where employees claim HMRC mileage reimbursement; commercial installs requiring per-session energy billing; or any install where usage data is needed.\u003c\/div\u003e\n \u003c\/details\u003e\n\n \u003cdetails\u003e\n \u003csummary\u003eWhat does load balancing do and do I need it?\u003c\/summary\u003e\n \u003cdiv class=\"faq-body\"\u003eLoad balancing monitors the total electricity consumption at the property and automatically reduces the EV charger's output current when overall demand is high — preventing the main supply fuse from tripping. It is particularly useful where the incoming supply is limited (e.g. 60A or 80A single-phase), or where an electric shower, oven, or heat pump may run at the same time as the charger.\u003c\/div\u003e\n \u003c\/details\u003e\n\n \u003cdetails\u003e\n \u003csummary\u003eWhat is the difference between this and the IP65 version?\u003c\/summary\u003e\n \u003cdiv class=\"faq-body\"\u003eThe two products are identical in function and available options — both include PEN fault detection as standard and offer the same surge protection, kWh meter, and load balancing extras.

A compliant PEN fault detection device is a recognised alternative to an earth rod under BS 7671 Amendment 2.

PEN fault detection monitors for a broken or disconnected neutral\/earth conductor (a PEN fault), which can cause the vehicle chassis to become live. Surge protection (Type 2 SPD) diverts transient overvoltages — from lightning or grid switching — safely to earth before they can damage the charger's electronics. This unit includes both in a single enclosure.\u003c\/div\u003e\n \u003c\/details\u003e\n\n \u003cdetails\u003e\n \u003csummary\u003eDo I need a 3-phase unit or a single-phase unit?\u003c\/summary\u003e\n \u003cdiv class=\"faq-body\"\u003eIf your supply is 3-phase, you need a 3-phase PEN fault detection unit regardless of whether the chargers themselves are 3-phase or single-phase. This unit is available in three variants: protecting 2 or 3 three-phase chargers (11 kW \/ 22 kW each), or up to 6 single-phase chargers (e.g. 7 kW each) all fed from the same 3-phase supply.

A PME (TN-C-S) supply has a combined earth and neutral conductor running from the substation.

The 4-pole variant is for three-phase (400V) installations — it monitors all three phase conductors plus neutral. Use 2-pole for standard domestic EV chargers and single-phase heat pumps. Use 4-pole for three-phase EV chargers (11–22kW), three-phase heat pumps, and commercial installations.\u003c\/div\u003e\n \u003c\/details\u003e\n\n \u003c\/div\u003e\n\n \u003ch2\u003eRelated products\u003c\/h2\u003e\n \u003cdiv class=\"eh-links\"\u003e\n \u003ca href=\"\/products\/pen-fault-detection-with-surge-protection\"\u003eSingle Phase PME Unit (IP65)\u003c\/a\u003e\n \u003ca href=\"\/products\/3-phase-pme-40a-rcbo-surge-protection\"\u003e3-Phase PME Unit\u003c\/a\u003e\n \u003ca href=\"\/pages\/ev-charger-consumer-unit\"\u003ePre-Fitted Consumer Units\u003c\/a\u003e\n \u003ca href=\"\/collections\/wced-products\"\u003eAll WCED Products\u003c\/a\u003e\n \u003ca href=\"\/pages\/product-finder\"\u003eProduct Finder\u003c\/a\u003e\n \u003c\/div\u003e\n\n \u003cdiv style=\"margin-top:16px;\"\u003e\n \u003cspan class=\"eh-badge\"\u003eType B RCD\u003c\/span\u003e\n \u003cspan class=\"eh-badge\"\u003e2 \u0026amp; 4 Pole\u003c\/span\u003e\n \u003cspan class=\"eh-badge\"\u003e25A \/ 40A \/ 63A\u003c\/span\u003e\n \u003cspan class=\"eh-badge\"\u003e30mA\u003c\/span\u003e\n \u003cspan class=\"eh-badge\"\u003eDIN Rail\u003c\/span\u003e\n \u003cspan class=\"eh-badge\"\u003eIEC\/EN 62423\u003c\/span\u003e\n \u003cspan class=\"eh-badge\"\u003eEV Charger\u003c\/span\u003e\n \u003cspan class=\"eh-badge\"\u003eHeat Pump\u003c\/span\u003e\n \u003cspan class=\"eh-badge\"\u003eUK Stock\u003c\/span\u003e\n \u003c\/div\u003e\n\n\u003c\/div\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n \"@context\": \"https:\/\/schema.org\",\n \"@type\": \"FAQPage\",\n \"mainEntity\": [\n {\n \"@type\": \"Question\",\n \"name\": \"Does every EV charger need a Type B RCD?\",\n \"acceptedAnswer\": {\n \"@type\": \"Answer\",\n \"text\": \"No — it depends on the charger.
