Whitecliffe WPRC40CSP: IP65 Weatherproof Consumer Unit with 40A Type A C Curve RCBO & SPD for Outdoor EV Charging

Safeguard your outdoor electric vehicle charger installation with the Whitecliffe WPRC40CSP protection unit. This unit features a robust IP65 rated weatherproof plastic enclosure, making it ideal for external mounting. It comes pre-fitted with a 40A Type A C curve RCBO and a Type 2 Surge Protection Device (SPD), providing comprehensive safety for your EV charging circuit.

All-in-One Protection for External EV Circuits

Designed for convenience and safety, this unit combines multiple protective functions. The core component is a 40 Amp Type A C curve RCBO, offering both overload/short-circuit protection (C curve characteristics suit circuits with moderate inrush currents) and sensitive earth leakage detection (30mA AC and 6mA DC) crucial for EV chargers. Additionally, an integrated Type 2 SPD guards against potentially damaging voltage surges.

IP65 Weatherproof Enclosure

Built for outdoor use, the WPRC40CSP features a durable plastic enclosure rated at IP65, indicating protection against dust ingress and water jets. As detailed in the product information, this makes it suitable for mounting externally where protection from the elements is necessary. The enclosure includes internal earth/neutral bars for tidy wiring.

Fault Indication and Compliance

The high-immunity Type A RCBO is specifically designed for EV charging loads. It incorporates a twin-handle system which visually indicates whether a trip was caused by an overload/short circuit or an earth leakage fault, aiding diagnostics. This unit helps ensure compliance with relevant electrical installation standards for EV chargers.

"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."
