that's because its perfectly acceptable to do them all together. if any circuit has low IR, another testing multiple at the same time...

maybe they didn't have any blanks

if that was you initial proposal, then you need to stay away from anything more dangerous than a dead AA battery

still wrong. move the wire from L1 to com. you're not changing where the power goes. PL is permanent unless its switched off for test...

PL. permanent live. the clue is in its name. the only switch in the PL is the test switch (which you don't have). you should also wire...

could be any combination... should have took note of which one was which before you ripped the old one out. now you'll have to test it...

an apprenticeship is 4 years. do you really think a 6 week 'intense' course is going to be much use? all you get taught is enough to...

do you want the the MCB rating to exceed the max total of 13a x however many sockets too, just so they can all be used at the same time?

you can't plan for every future possible use of the socket

of course i won't try that at home. i don't have any 3 phase sockets there now at work i do have a suitable socket...

simple voltage tester will do there is only so many combinations, however get them wrong, and chances are you've damaged the PCB so...

here's mine

you need to do some actual testing of the cables coming in to see which cable does what. winging it and randomly trying different...

yes, providing the cable is protected against overload / fault currents

if you know enough to know a photo won't help, then you wouldnt need to be here asking questions in the first place
