Electrical Troubleshooting Guide (Residential)

1. Power Outlets Not Working
✅ Check:

Tripped breaker → Reset panel breaker.

GFCI tripped → Reset all GFCI outlets on the circuit (often in bathrooms, kitchen, garage).

Loose wire in box → Turn off power, pull outlet, inspect backstabbed wires.

Burned outlet → Replace if blackened or cracked.

2. Circuit Breaker Keeps Tripping
✅ Check:

Overload → Too many devices on one circuit.

Short circuit → Burned wire, screw touching box.

Ground fault → Use GFCI or breaker tester to diagnose.

Appliance fault → Try unplugging all devices and testing again.

3. Lights Flickering

✅ Possible Causes:

Loose bulb or socket → Tighten or replace.

Loose wire in switch or fixture → Check wire nuts and connections.

Voltage drop from large load → A/C or pump starting? May need dedicated circuit.

Bad switch or dimmer → Swap it out.

4. Light or Outlet Doesn’t Work But Breaker is ON
✅ Check:

Neutral wire loose or disconnected

Backstabbed wire pulled out

Bad switch or receptacle → Replace.

5. Burning Smell or Warm Outlet
✅ STOP and check immediately:

Loose connections → Causes resistance and overheating.
