Hello all! Would some kind sparky type have a quick look at this and give me some practical advise?
We have a problem with a supply: a distribution board with 30A BS88 fuses supplying a consumer board of 63A RCCD feeding two MCBs of 32A (has a total28A load) and 16A (2Amp load). The connection between the two is wired in 20 meters of 2.5mm2 twin & earth. Is this OK? I ask because the 28A load (Switch mode power supplies) causes all sorts of flickering and volt drops across the other load at switch on and usually will not power up (unless individual equipment is powered up one by one).
My questions are: Is this cable OK? What size should the cable be?
Thank in advance for any help given! Jake
