The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
What happens if you mix up hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.
Which is the hot wire brown or blue?
Brown is your hot wire so you want to connect that to your building’s black wire. The blue is negative or return, so that will go to white. Green with yellow stripe is the ground and will go to the building green.
