so can anyone see a problem with a ufh system on its own circuit with a 6amp mcb rcd protected, with a thermostat that is rated at 16 amps max and ufh cable producing 750watts?!?!

it says the thermostat is rated for 16amps max

so what would u recommend its easier to install it straight to the board with an mcb rather than feed the cable through the wall for a fused spur

still mentions 16 amps

it says you can use a fused spur on an existing circuit but the other circuits are not rcd protected and only mentions a double pole switch for larger installations

i appreciate its advisable to follow the manufacturers instructions but surely its better practise to use a lower rated mcb where appropriate

the instructions state there is enough to heat 5 sqm with a sqm metre using 150 watts, im not using the under floor heating to heat the room its already got a radiator and towel warmer in there,

yea the fridge is on the socket and the lights in the kitchen are also on a seperate circuit. My theory was maybe one of the bulbs blew in the kitchen which caused a surge and blew the other one which was probably on its way out anyway and the fridge bulb just blew coincidentally, changed the...

bought some under floor heating and it states a 16amp mcb is required but looking at the power output it is only 750watts will I be ok with a 6amp breaker? my calculations are saying a 6 amp is ok but wondering why the instructions are stating 16 amps?

Hi can anyone explain to me what this could be. Ive recently done some work on an upstairs lighting circuit and I isolated the mcb and did the work turned the circuit on no problems afterwards I noticed 2 of the spot light bulbs on the downstairs lighting circuit had blown and the fridge bulb...

can anybody tell me where I can get adaptors for a multi function tester for testing light circuits through the fitting without having to remove the fitting for doing earth loop tests etc

ok thanks for that

Hi, New 9.5kw shower being installed with 10mm cable, clipped direct, rcd protected and its being notified through building control. The consumer unit is a square d and ideally I am after a 45 amp mcb for it but I am struggling to find one. The local electrical wholesaler recommended a...

lol it was just an example so i havent really got to worry to much then

How many lights can safely be spurred off one light switch for example a bedroom with 12 x 240 volt down lighters

what are the risks with parralell cables

see im thinking to have somone in to do a periodic or just have someone to rewire the sockets whats gonna be cheaper

no when all 3 are disconnected they are dead but add any 1 and all three become live

either way it sounds like a bodge job to me more importantly how would this effect a periodic inspection

so could it be possible that they have run a circuit under the floor and just spurred off it and maybe parralel cables hence the 3 lives?
