Troubleshooting Wire Extensions
Listed below are some widespread issues which will happen when extending electrical wires:
1. No Energy to the Extension
Verify if the facility supply is turned on and if the extension is correctly plugged in. Examine the wire for any seen injury or unfastened connections.
2. Dim Lights or Home equipment
The wire could also be too skinny for the load. Improve to a thicker wire with a decrease gauge quantity (e.g., 12 gauge as an alternative of 16 gauge).
3. Sparks or Arcing
A unfastened connection or broken wire could cause sparking. Disconnect the extension and tighten all connections. If the wire is broken, exchange it.
4. Overheating
Overloading the extension with too many home equipment or gadgets could cause it to overheat. Scale back the load or improve to a higher-rated extension.
5. Tripped Circuit Breaker
If the extension is drawing an excessive amount of energy, it could journey the circuit breaker. Reset the breaker and verify the wire for any points.
6. Brief Circuit
A brief circuit happens when the constructive and unfavorable wires contact. This will trigger a fuse to blow or a circuit breaker to journey. Disconnect the extension and discover the quick.
