MCCBs

Ok, no showers on this one.

Where can I find max zs and time current characteristics for mccbs.

There's nothing in the BBB covering them (as far as I can see).

Thank you.

Thanks Alasdair and Mike,

That confirms what I believed to be the case.

The one project this involves has 3 distribution points before the final distribution boards.

My guess is the client's plan is to use:

Main Supply - BS 88 Switch Fuse

Main Dish Board MCCBs or MCBs

Sub Main Boards MCBs

Final List Boards MCBS.

I will probably recommend:

Main Supply BS88

Main Dist Board BS 88

Submain Board MCCBs

Final Dist Boards MCBs.

Is this something you'd agree on.

Best,

Richard.
