110v supply issue?

[Steve46]

just a quick question I’ve searched online but want to be sure before deciding what to do.

I am putting in a supply for x5 110v commando sockets in a workshop.

The commando sockets each have a internal 16amp double pole MCB inside the socket.

I’ve wired from the DB a 32amp 10mm2 supply to a centre tapped transformer as per drawing.

From here I was unsure how to wire out to the x5 commandos.

So I ran a cable from the transformer in to a small 6 way DB and and fed the commando sockets from there the issue I have is that I’ve used x5 16amp single pole MCBs, then thought that they might need to be double pole MCB’s.

Would I need to change the small Db for a larger one and feed the commandos with x5 double pole MCBs?

thank you for your time and have a great day ??

It is showing a 10 way dist board with 16A type C protective devices. It doesn't indicate whether single or double-pole devices but it should be double-pole.

Oddly it is not showing MCB specified at the sockets, unless that is specified off-page or in the list of parts?

Certainly the ideal solution to me would be a board right next to the transformer (less than 3m cable) and all DP MCB there.

You don’t need mcbs at the socket positions if you have DP mcbs at the origin of the circuits

The spec is poorly worded indicating single-pole and neutral, it should say two-pole and earth.

Indeed not, but the OP said the sockets had integrated MCBs which is a cause of confusion here.

You’re correct, missed that , apologies
