I plan to upgrade my current small consumer unit and install a larger one that will allow me to split the load and wire the lights/smoke detectors direct and not via the RCD as is currently the case. (The previous owner has wired everything through the RCD).
My current installation does not have a main switch other than the RCD one so how do I turn off the supply to install the new unit. Is is common practise to phone my supplier and ask for the supply to be turned off for 30 minutes. ??
Grateful for the advise of the experts.
Thanks
