Crossy Posted June 7, 2015 Share Posted June 7, 2015 Does the one in the picture protect overload or only leakage? Yes, it's an RCBO so overload as well as leakage. Link to comment Share on other sites More sharing options...
stubuzz Posted June 7, 2015 Author Share Posted June 7, 2015 Could i use this as the main breaker. It does not specify overload . Link to comment Share on other sites More sharing options...
Crossy Posted June 7, 2015 Share Posted June 7, 2015 Could i use this as the main breaker. It does not specify overload Yes, it specifies "C32" which would be a C curve 32A breaker so it includes overload. Link to comment Share on other sites More sharing options...

stubuzz Posted June 8, 2015 Author Share Posted June 8, 2015 Just had a look at the Safe T Cut breakers ( see post 25) it looks like the neutral wire has to be grounded. Is that right? Link to comment Share on other sites More sharing options...

bankruatsteve Posted June 8, 2015 Share Posted June 8, 2015 Not on mine - but mine is 35 years old. Do you have to wind it up? Link to comment Share on other sites More sharing options...
lopburi3 Posted June 8, 2015 Share Posted June 8, 2015 No and it still works fine - this is one area that Thailand was ahead of much of the world - now if they would only require ground wires. Link to comment Share on other sites More sharing options...
Crossy Posted June 8, 2015 Share Posted June 8, 2015 Just had a look at the Safe T Cut breakers ( see post 25) it looks like the neutral wire has to be grounded. Is that right? PEA and MEA insist on MEN (grounded neutral) connection for new installations and won't connect a permanent supply if it's not implemented. If it's an existing system my usual advice is DO NOT ground the neutral unless you KNOW that MEN is implemented in your area, the earth leakage portion of the Safe-T-Cut will work just fine without the N-E link. If you see a ground spike connected to the neutral wire on every 3rd pole or so you have MEN so a N-E link will improve the overall safety of your installation.
