The future of residential building electrical installations

Arran Cameron
This is a spin-off from the discussion What is the best way to wire ceiling lights.


What do you think is the future of residential building electrical installations in 20 to 30 years time? Will they in modern and modernised houses be significantly different from what they are today or will they most likely be barely changed from what they are today?


Will consumer demand be a driving force for change or will electricians only make changes from the status quo in order to comply with updated wiring regs?

    The existing distribution network will probably melt if everyone tries to draw 60 amps, it’s four times what the system is designed to deliver to each house.






    And the rest ! The correct factor will be more like ten times, i.e. 6A is nearer where the network feels the pinch. Luckily we cannot generate anything like enough to actually supply everyone with 60A, so melting the network is not a risk, except in a few places.

    Consider total generation of about 50GW all turning  more or less flat out and supplying 30 million households. If we turn off all shops and industry, all hospitals and all streetlights, we might get to 1.7kW, or about 6 to 7 amps,  per house.

    There really is not an awful lot of slack.
