i have been tasked with a design of protection, metering and control(PMC) relay panel extension to accommodate all PMC relays.There is an already existing panel where this one will be built.What are the design aspects for this kind of project? thank you.
what is the voltage between earth to neutral in lift.
In Indian Household, generally we receive 220V AC single phase supply. But AC has 2 phases, +ve & -ve. So in +ve half cycle current is flowing...so what happens in the -ve half cycle?? Please illustrate.
