fused spurs

[ShaunCorbs]

Good example of how a simple question can involve complex considerations. Next someone will ask is the cable surface mounted or surrounded by rockwool.

or chased in 😀

Sorry, I thought the 1.5mm was also t&e, 1.5mm flex is very big for a boiler,

That's why I said ref.method C

nope always use 1.5mm for boilers

0.75mm is more than big enough for a boiler, it's rated at 6 amp capacity

No, the 15amp protects the circuit the 3amp protects the appliance fitted, in this case the boiler

Always thought the fuse was there to protect the cable so the fuse melts before the cable.

yea doesnt mean i agree with it

As above thought the 1.5 was t&e to the spur not from the spur to the appliance, you are right,

Was t+e to the boiler.

 

[ShaunCorbs]

Was t+e

why would you use t+e from a fused spur to a boiler

 

[stani]

So have you taken 1.5t&e into the boiler

Cables are often oversized. I never use any heavier cable to a boiler than 1.0mm and that is more than plenty.
Fuses are for protecting cable to appliance and, perhaps slightly less importantly, the appliance itself.

Correct, the appliance has its own protection - a boiler for example usually has a terminal block with its own fuse in it.

T&E cable from a spur to a boiler is fine, providing you use a wiring box, or another spur to take white 3 core round cable into boiler

 

[stratplus]

So have you taken 1.5t&e into the boiler

I havent done anything, this is just one ive came across that has got me thinking. But yes t+e into boiler. Mi's say at least 0.75mm pvc insulated cable....dosent say you have to use flex.

 

[MOSSEP]

To throw a spanner the works, you could feed an FCU with a run of 1.5mm t+e clipped direct from the consumer unit and protect it with a 16A 60898.

dude it sounds like your out of your depth, from the fused spur to the boiler use flex looks much better and you wont have any problems with the glands on the boiler
