What is L and N reverse?
If your outlet’s polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is.

What happens if neutral and hot are reversed?
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.
How much does it cost to fix reverse polarity?
Repair / Replacement Prices for Common Problems
| Roofing | |
|---|---|
| Rewire / correct electrical outlet with no ground /reversed polarity (minus service call fee) | $10.00 to $15.00 each |
| Replace circuit breaker | $$75.00 to $125.00 |
| Insulation | |
| Insulate open, accessible attic are to modern standards (R 31 or better) | $1.50 to $2.50 per SF |
Will reverse polarity trip a breaker?
Reverse polarity will not trip a breaker. Only a dead short will. Pull the receptacle out and give us clear pictures of all the wires and connections. It sounds as if you have connected the grounded neutral conductor on that circuit to the hot wire, probably at the receptacle terminals.
