38A mcb?!

[extremeds]

Anyone else come across one of these?
38 amp MCB. It's an old proteus centaur. Looks very similar to old crab tree breakers. But I've never seen or heard of that rating before.

I did think id seen it on the Green Onsite guide (not sure where i put that) but on the Yello talks of 30 32 and 40 MCBs
What was it supporting, out of intrest

Can't see any mention of them in the green OSG.

No mention of them in 16th edition OSG either

Never seen a non adjustable 38A mcb, maybe it was specially made for a 6.0 T&E which in general terms is not rated at 40A.

 

[telectrix]

check cable size and installation method, load current, and then replace with either a 32A or a 40A as required.

Yep my school, all the rings had them as did 4mm' pyro for stage lighting which had a 30a isolator.
