3 phase swa sub

[tukovepo]

Just a quick one does a three phase 25mm sub main in swa 4 meters long have to be fused even thou it comes from a bs1361 100amp services fuse then from a standard three phase isolation switch fitted from electricity company? Being swa and 25mm in size would this be acceptable?

Is this in Germany or the UK.

 

[cliffed]

I would say yes

Assuming this is UK and not Germany then the maximum length of tails that can be protected by the suppliers fuse is 3metres.

It's up to you whether you think it's acceptable to stretch this rule or not for the situation.
