&$&$ Electrician

Pull stove, install backsplash, grout. Push stove back, won't slide very easy, tilt it forward with one hand on the top, leaning the door against my kneepads to push it back. I placed my other hand against the microwave above to get some leverage and ZAP!

Turns out the stove and microwave, both stainless, are on the same circuit and the hot and neutral are reversed on the microwave outlet.

My preferred method of testing a circuit is one of those plug ins with the 2 amber and 1 red light.
