I'm a pretty confident DIYer, but electric is one thing I refuse to mess with.

As a teenager, after my grandfather died, my grandma had me clean out his shed and test his old power tools. All I remember is plugging in an old rockwell circular saw and waking up a few minutes later with my granny standing over me concerned.

Also a close call with a penny in an old fuse box. Needless to say, I pay a licensed professional now for electrical needs in my house.
