Definitely was inside heard it clearly there was smoke and everything. Now I think of it I remember them saying the clamp of one of the earth wires that’s been added, maybe when the ev charger was installed, might have been put on too tight.

I’m not sure but whatever happened it was inside the house. The fuse might not have blown but something went bang in the black box in the lower left corner of the picture in my first post.

They think the live and neutral on the incoming cable might have touched together, could have been a lot worse, fire etc. Drive’s all been dug up old cable cut and a new length of swa cable connected and brought in to the house.

Thanks yes will be calling 105, was wondering if I need to call immediately or in the morning. I don’t believe there’s any immediate danger so will do it first thing There is an EV charger but it wasn’t in use at the time. Other one goes to the loft conversion I think. There is a breaker...

What should I do if my incoming mains fuse blows? I heard a bang and there was smoke in the meter cabinet which is where the mains enters the property and contains the mains fuse, electricity meter and consumer unit. None of the consumer unit breakers had tripped. I have manually switched the...

To update, installer has been out, checked for loose connections, tested the wiring and replaced the rcd. I noticed that under the original fault after tripping the MCB was warm/hot to the touch after the shower had been running. While the replacement remains cold, so seems like faulty breaker...

Oh, yeh, it’s in a loft extension they ran the cable up the outside of the house rather than internally

Steel wire armoured, the heavy cable going in to the consumer unit.

No, it’s an entirely new en suite, including the swa brought from the supply and consumer unit.

Can confirm it’s 8.5kw

Ok thanks will try to amend my OP. With a short circuit would it be likely to run for 5 mins before tripping?

Newly installed Triton T80 8.5kW shower. The shower is tripping the MCB after about 5mins of use since it was installed. It’s on an 40A MCB which feels warm to the touch after it trips. Appears to be 6mm cable, the consumer unit is less than 18m away. No sign of water leaks, completely dry...

D'oh, why didn't think of that! :rolleyes:
