HI,
I decommissioned my electric shower so there is nothing attached to that 30A circuit. I want to add a load of lights to the master bedroom/ensuite which will (at full load) overload the exsting 5A lighting circuit. I can't add a new circuit to the consumer unit, plus the cables exiting the consumer unit are chased in to the plaster which I don't want to rip out.
Is there a good reason not to connect my new lights to the currently-unused 30A cable? Should I change the 30A fusewire for 5A if I do connect them? IE, have 5A fusewire connecting to some 30A cable which connects to 5A cable which supplies approx 1kw max load of lighting.
Also if in the future I upgrade my fusewire consumer unit to one with MCBs will any decent sparky (i'm wouldn't install the new CU ) refuse to connect 30A cable to a 6A tripswitch?
Thanks a lot.
