Sub panel: Underrated MCB?

[Ray Pooley]

Hello all

A quick question about an existing layout if I may.

The layout consists of a main CU connected to a sub panel via a single 63 amp MCB.

A Dorman Smith K1PC63 to be exact.

Total potential load on the sub panel is 25Kw.

Routinely all of that load is present on the sub panel throughout the day apart from two dishwashers (10 Kw) which are in service for about 25% of the time.

What do you think about that MCB? Underrated given the load or adequate?

I have my own opinion which is it should be considerably higher. Also, possibly, the cable that connects the two but I don't know about that because I haven't looked at it.

But I would like to hear your opinions if that's ok.

Cheers.

Actually, I was thinking exactly the same thing about the guy who implemented this crap. MCBs the wrong way round etc. Different folks have different standards I guess.

With the questioning and extra information you have supplied after my earlier comments, it has become clear you are out of your depth here, you are taking on an advisory role without the knowledge to give an informed opinion, the fact we have had to explain what I would class as basic electrical knowledge for anyone in your position is somewhat disturbing, my original help was given as I thought you were in a position of say a maintenance person with a keen interest etc without any formal training hence my advice to get an inspection done, as it has become clear you have been called in to assess and report on this installation yet lack basic understanding of even the operation of an MCB then I can only come to the conclusion that this thread needs closing and you need to get a competent knowledged person in... you have provided enough responses in my mind to establish you are not competent.

Thread closed.
