60 amp service fuse

[Electro]

I have a 60 amp service fuse can I have a 9.6kw shower fitted or do I need to call the DNO's to change the fuse.
thanks in Advance Dave.

Well, you could start with telling us how big your house is, and what other electrical items you have.

60amp is a little small, but was very common until recently. Most DNO's fit 80amp fuses these days (even though the actuall carrier says 100).

your shower will take around 40amp, leaving 20amp to play with. Not a lot. What will be used when you are showering? Elec Cooker?? Elec Heating??

you cant be sure it is 60 without looking. might be 80 or even 100. best just leave it til it blows, then DNO will probably fit higher rated fuse.

just to show your chances of blowing it, my house (old TT wiring in the middle of no-where) only has a 40A fuse. and not once has it blown in the 15+ years ive lived here. and that has a 9.5KW shower and elec cooker is sometimes used

Thanks for the replies, no electric cooker not to say their won't be one in the future 3 bed semi, no emersion heater but do have gsh run on a 16amp breaker. is this enough info.
Thanks

as lectrician says, you cant be sure its a 60A fuse really.

think the DNO call out time is only 3 hours anyway should you end up blowing it!

Most DNO's fit 80amp fuses these days (even though the actuall carrier says 100).

Actually, the only 80A main fuses I ever come across are postitively ancient. They are BS 88s as (AFAIK) 1361s don't come in 80A. Every new fuse I have encountered has been 100A 1361 Type II, exactly what it says on the 'tin'.

but do have gsh run on a 16amp breaker.

If gsh means Gas Central Heating, then 16A sounds like too high an MCB for it.

If it's "good sense of humour" then 16A is probably ok.

If it is a 2.5mm² radial circuit feeding an FCU then a 16A MCB is absoloutly fine.

 

[securespark]

As long as the CH is fused down to a maximum of 3A.

Erm, a naive question: how do I tell the rating of my service fuse?

 

[RF Lighting]

You can't.

(Unless you snip the metal seals, pull the fuse out, unscrew the carrier and read what is written on the actual fuse, but this is both dangerous and an offence)

 

[Softus]

You can't.

Oh my. I was only asking.
