BS7671 Amendment 2. Off-peak E7 consumer unit RCD and SPD.

Sparkingchip

Two new consumer units, peak and off-peak each remote from the intake with seventeen metre SWA distribution circuits.

The peak consumer unit will have Type A RCDs and a Surge Protection Device, is the off-peak consumer unit okay with a Type AC RCD and does it need another Surge Protection Device?

Andy.

    Unless the heaters need an RCD for fault protection, installation method or manufacturer recommendation, i would be inclined to omit it. If you are going to fit one, check with heater manufacturer what type they recommend and amount of DC leakage per heater.

    The cost of the heaters against the cost of an SPD+mcb means i would recommend to the client they be fitted. The SPD may be fine protected by one of the heater's 16A mcbs, That way if it trips it will be noticed, and it will save a few quid, plus less ways in the CU
