Hello All

Been asked to install some power in a basement in a commercial building to supply some temp computers are floor is on the 2nd floors 4 floors above the basement taking into account the mezz floors so it will be a tricky run.

So we have to come off the landlord board in the LV switchroom.

I was thinking of running a 4mm swa on a 40A type C MCB into a metal merlin gerin board then from the board run 2x 4mm 32A radials on tray supported to the ceiling. then prefabing some tray and unistrat then mounting the sockets onto that.

The landlord has asked for and isolator to be installed nxt to the board so when the desk are removerd after 6weeks we can look it off the monitor furture use on the ccts.

any thoughts

Why a C type breaker.

Be careful on the amount of computers on that circuit as the 4mm Radial will not give you an high integrity earth.

All the other mcbs are merlin gerins type C shouldnt be that many computers really guessing no more than 10 and two on at a time the IT department are using them to upload new data etc.
