Safety of changing a dimmer switch
I recently had my bathroom remodeled and a Lutron dimmer switch (single pole) installed. I think it's a Skylark, slide to on/off. I don't care for that type of action so I'd like to replace it with a Diva.
I've watched the Lutron how-to video a number of times and it looks easy. But I'm terrified of electricity. Terrified. When I turn the power off at the breaker box, am I gonna be okay? I bought a no contact voltage tester. Can they be trusted?
The day the guy installed the dimmer switch, he did not turn off the power at the breaker box. How does that happen?
