    triple pole mcb rip off

    don't use rcbos for TT

    Sorry meant to say live..rather than line, neutral IS classed as a live conductor. And without getting too ---- about the whole thing....We have to consider all possible scenarios. We may wish to do work to a particular circuit without turning off the whole board.It is unlikely that all circuits...

    Medical areas

    I'm wondering have any members got any experience with testing in group 2 medical locations?specifically I was wondering how to go about testing the anti static flooring.There are copper tapes coming out of the vinyl flooring which I'm guessing have to be terminated to 4mm earth cables and run...

    don't use rcbos for TT

    I think they are......In a TT installation neutral is also classed as a line conductor,And as such if isolation to a particular circuit is required for maintenance or alteration we are supposed to be able to isolate both poles without having to knock the whole installation off via the mainswitch...

    Cannot get RCD test to work?

    Try testing live (load side) to earth only(neutral and earth probes) Did an rcd spur work out cheaper than fitting an rcbo at the board?and where did you site it?Above the ceiling?

    dear motor experts

    What’s a commercial kitchen got to do with a boiler house? Nothing pal,I'm out of the plant room and into kitchen now..So just to reiterate we are now saying that most modern switches,isolators disconnectors,or whatever they are now called with a marked neutral will have an early make late...

    dear motor experts

    so.....I'd assume then that the main isolator at the dist board where everything is fed from shouldn't be switching the neutral either? which it is, and possibly the mccb feeding the sub main too...all these in theory could have the same effect.....floating neutral? and what about commercial...

    dear motor experts

    I wonder have any of you motor experts any thoughts on this.I was testing a plantroom today with many 3phase isolators fitted for pumps and panels etc. The isolators used were 4 pole rotary type(20 amp mostly).The installing electrician who wasn't present had connected up only the three phases...
