I do my own electrical work except for three-phase (240v).

Within the last two years, I knew the line going to my dryer
was problematic. It was just a matter of replacing the line
from the box to the outlet - less than 40 feet. I paid
someone to do it. That's how afraid I am about three-phase.

Electricity kills people and burns down houses. If you do
not respect it, you could die from either the shock or
smoke inhalation.
