Hi folks,
I recently lifted some floorboards in a bedroom, to reveal the tangle of cables and 'floating' JBs that make up my fixed wiring. My house has a kitchen extension, and the power ring circuit for this seems to come from one of these JBs, as two 2.5mm2 cables. This JB is connected to a second JB, on one of the main rings, by a length of heavier cable ( 4mm2 or 6mm2, not sure). So it looks as though the entire ring circuit for the kitchen is wired as a spur from the main ring. I have never seen this method of extending a ring described in books - does it comply with the Regs?? The kitchen ring powers 5 x 13A sockets, a FCU to a dishwasher, a FCU to a 1kW water heater and a FCU to a 150W towel rail heater: so I guess the 4/6mm2 cable is not overloaded (it's been like that for years!). BTW I checked that the circuit is a ring, not a 'tree' spur.
Never look under the floorboards - there are things there that mere mortals should not see!!
