Discuss 1.25 flex of a 13 amp fused spur feeding a 3KW immersion heater in the UK Electrical Forum area at ElectriciansForums.net
Only for post-FCU use where not "fixed wiring"1.25 is a fairly non standard size imo which is usually found on extension leads and 4 way plug adaptors etc
Agreed!1.5 should be used for fixed hook ups like immersions and storage heaters imo
Cheers Brian I thought overload protection wasn’t required. Looks like these were initially installed like this.If it's on a 16A circuit, then the fuse in the FCU is not required, so the FCU should be replaced by a 20A DP switch. A 13A fuse will run hot feeding a 3kW immersion heater, and the plastic of the FCU will be damaged over time.
