bepgof 20 Report post Posted June 2, 2012 What happen if I install 10 13A SSOs in single loop using 16A MCB and 2.5mm wire?2 things happen: something happens and nothing happens. I've said 2.5mm cable can carry contineous 5A safely. This size can carry 230 x 5 x 0.8 = 920 watt of load!I've also said, PVC cable insulation can last up to 70 deg C (actually this is the "design temperature"), practically, pvc lasts till 105 degC, before its electrical characterists varnish/give way.As rule of thumb again(cos too many copper alloys in mkt) if current capacity up to appro 6 times its mm sq size (2.5 x 6 = 15A) it will reach 105 degC within seconds!.

Thanks in advance! Edited May 24, 2013 by kevenang Share this post Link to post Share on other sites
