Whitecliffe WPRC40BSP: IP65 Weatherproof Consumer Unit with 40A Type A B Curve RCBO & SPD for Outdoor EV Charging

Install your outdoor electric vehicle charger with confidence using the Whitecliffe WPRC40BSP protection unit. Featuring a robust IP65 weatherproof plastic enclosure, this unit is purpose-built for external mounting. It includes a pre-fitted 40A Type A B curve RCBO and a Type 2 Surge Protection Device (SPD), providing essential, compliant safety for your EV charging circuit.

Combined Protection for Outdoor EV Installations

This unit offers a streamlined approach to safety. It integrates a 40 Amp Type A B curve RCBO, which handles both 40A overload/short-circuit protection (B curve is typical for domestic circuits with low inrush current) and sensitive Type A earth leakage detection (30mA AC and 6mA DC). Alongside the RCBO, an integral Type 2 SPD provides crucial protection against voltage transients.

IP65 Weatherproof Design

Specifically designed for the demands of outdoor installation, the WPRC40BSP utilises an IP65 rated plastic enclosure. This rating ensures protection against dust and water jets, as detailed in the product information. It's ideal for mounting near driveways or external walls where EV chargers are commonly located. Internal earth/neutral bars are included for ease of wiring.

Fault Diagnosis and Compliance

The included high-immunity Type A RCBO is well-suited for EV charging applications. It features a helpful twin-handle mechanism – if only the black handle trips, it suggests an overload, whereas if both handles trip, it indicates an earth leakage fault, assisting with troubleshooting. This unit helps ensure your installation complies with relevant electrical safety standards.

"Ordered a Hypervolt charger, power cable and a fuse box. Waited a week to be told that both the cable and fuse box were out of stock. They upgraded the cable from 4mm to 6mm at no extra cost as the 6mm was in stock, however the cable supplied was Prysmian rather than the Doncaster Cables EV Ultra that was actually advertised on the website. The fuse box I found cheaper elsewhere so they cancelled and refunded that part of the order. Easy and helpful to deal with but could be better on the communication and keeping the stock situation up to date on the website."

"I ordered the Ohme Home Pro 5m Smart EV Charger from Evergy as they offered the best price online. From the initial order to the product arriving (within a few days) it was effortless. Thank you."
