    Hi! Could any electricians estimate how long it would take to replace 4 consumer units.

    The consumer units are in outdoor buildings, each running minimal lights & 2 plug sockets. The cables are all in place, it's literally just replacing four old consumer units with new ones. Tia!

    Why neutral and hot reversed only when a/c is turned on?

    I have tenants that have 3 fairly new small a/c units all the same and when any of them are turned on my tester reads hot & neutral reversed. The 15 amp circuit that feeds these units has no ground wire. Is this normal or could these a/c units be wired wrong from the factory?
