S.P.D.s and Populated Consumer Units.

Zoomup
Are new populated consumer units with S.P.D.s fitted designed to mainly protect the sensitive electronic equipment downstream of the S.P.D.s WITHIN THE CONSUMER UNIT? Is that the makers' MAIN intention as R.C.D.s, R.C.B.Os and other sensitive electronic devices can be damaged by Voltage surges, as compared to basic protective devices like wire or cartridge fuses or more basic M.C.B.s?

    I recently installed a domestic SPD. The house was semi-rural, and definitely failed the risk assessment. As for the single-dwelling exemption: getting an SPD CU from Wylex adds about £100 to the cost. The cost of protected equipment: combi-boiler, TV, laptops x 2, smoke alarms, burglar alarm, phone chargers, LED lighting etc, easily worth more than 5 x £100. So I don't see how I could be compliant with 18th Ed without installing one.
