    MCB Rating - (Light Industrial)

    Evening

    Just finishing off the electrics in the unit.

    Im running a 180amp welder via a 32amp MCB (welder fused for 25amps)
    Im also running two lines of double sockets on series, each series has 4-6 double sockets - can i get away with 20amp MCB?
    The lights are in the same type of set-up (two lines in series) each series will run 4-6 standard 6 foot floresent tubes, can i get away with 16amp MCB?

    fr any help.

    It is all down to the cable used, not just the load. 16 amp for the sort of lighting you are talking about is very high, its usally 6amp on 1.5mm2 cable

    32 is ok for the welder if the cable you are using is 6mm

    That quantity of sockets should be on a ring with 2.5mm (maybe even 4mm if it is a very long run) cable and a 32amp breaker

    you must have been listening to a call i was just having...lmaolmao

    Welder is fine on 32 and using 6mm cable
    Sockets both to run on 32's (2.5mm2 cable) max run 12 meters each (shall look at changing to ring set up as might have a nice large roll of 2.5 coming)
    Lights 6 amps on 1.5mm2 same type of distance.

    yep....you know the wall on your right as you come into the unit i have done a run of plugs along there, then i need to rig something up to go over/across the rear doors to run another load on the opposite wall.

    welder has its on 240 shut off industrial unit switch.
