Can you touch wires when switch is off?
Unfortunately, it is unsafe to touch electrical wiring that is switched to off. The switch should either disconnect both live and neutral, or just live line. But you can expect some lighting to be mis-wired by switching the neutral, instead of the live line.
What happens when we turn off the main switch of the house?
The main circuit breaker, usually located inside the main panel at the top, shuts off all of the electricity to the house. In a dire emergency, this is the one to turn off. Otherwise, shut off only the breaker that serves the problem circuit—that way, other parts of your house will continue to have lights and power.
Is it safe to replace a light fixture with the switch off?
You can, but it’s not a good idea. Heck, you can change it with the power on, but that’s not a good idea, either. Turning off the switch will disconnect power, if the fixture is wired properly. Some still like to run a “hot” wire to each lamp, and switch the neutral, or grounded conductor.
Should I turn off main breaker during power outage?
Unplug everything in your home. Turn off breakers or remove fuses. If there is an extended power outage, you may want to leave one lighting circuit on so you will know when the electricity comes back on. If the power is not off there can be damage to the elements in the heater.

Do you have to turn off electricity to change a light bulb?
The best way to change a light bulb is to turn the power completely off. When I say completely, I mean to turn off the circuit breaker in the fuse box. Only switching the light switch off is not enough. If the switch is wired incorrectly, the positive will still be carrying current to the holder.
