Outspoken
Oh my God, seriously?
Slide the front off the 'neutral' side of the head, by the main fuse.
You will notice on the top of the head, next to where the neutral goes in, there is a little knock out. Knock it out.
Stick your cheese and onion in. You will probably need a hex hey to do up the terminals.
PME doesn't have a seperate terminal for earth, hence Terra Neutral Combined Seperate
That is all well and good and likely 100% correct (assuming they actually installed a PME service), BUT you do realise it is ILLEGAL to interfere with the service head unless your employed or given permission by the owner of that service.
It does nto matter what you personally do or what anyone would actually do, advocating breaking the law on a public forum should never be done or excused.
