garage cut out

[growler]

im running a 16mm armoured from existing house to new triple garage. the run of armoured is about 5 metres buried underground. do I need to provide an 80amp cut out for the swa as its going to come off Henley blocks ? sorry if this is a stupid question just lack a bit of confidence sometimes.

What is the current carrying capacity of the cable, including rating factors?

Put in a fuse with a lower value than that.

what do you mean cut out?, I would understand if you meant switch fuse.

 

[growler]

yeah switch fuse

you need to fit a D/P switch fuse or D/P switch and MCB. 1. for isolation, and 2. for fault protection. 80A is about right for 16mm SWA. but you could reduce this depending on the load in the garage and whether or not you can obtain a satisfactory value of Zs.

give it 63A top end...
more than adequate...

quite right tel..
theres this obsession that goes round that it has to be max all the time...cooker ratings threads spring to mind as well here..

better to give yourself an allowance

and if there were any questions asked...it was a case of `roll ends`....

the garage may be turned into a house in the future so wanted the supply to be adequate.

So why aren't you running 25mm?
