Let's say there's a socket and an appliance is plugged into that but the electrical connection to the socket is cut-off using a switch.
so there's a air gap and this should act as insulation and I need not to be concerned about lightning strike on the electrical line.
But there's a common sense to unplug during thunderstorm but I don't see any reason why should we do that because there's an air gap and no way electricity surge from the lightning strike is gonna jump through the air.
Someone help me understand this.
