Hi all....
I have installed a PIR floodlight at my industrial unit, there is a 3 phase dis board with single mcb's labelled L1, L2, L3.
I'm assuming the Live goes on to any of the spare mcb's - but can anyone advise where the neutral connects to, there are three connecting blocks under a cover labelled "neutral" - does it matter which one the neutral goes to or are they common? Likewise is it a common earth?
And if it is a job for a qualified sparky then tell me that too!
