Can anyone out there advise me as to why a 300 watt, 230 volt inverter run from a car battery has to have the neutral earthed?
It says this in the manual that came with the thing but doesn't explain why.
Many thanks. Len.
probally cause code calls for it code requires neutrals to be grounded on transformer secondary and service entrance to ensure no high voltage V1 gets over to v2 havent been able to get new 600 v delta from Toronto Hydro for years bless you Toronto Hydro
There's a good chunk in the Wiring Regs on generating sets (includes UPS's and any other source of electrical power). Earthing them correctly is a non-trivial issue.
