When a GFCI outlet trips, the outlets on the same circuit will stop working as well so it’ll be easy to tell which ones are on the same circuit.

If the GFCI outlet doesn’t have buttons, then it’s connected to a different GFCI outlet on the same circuit. Check around the same room or area of your home to see if there’s a GFCI outlet that has a “Reset” button.

If your GFCI outlet trips again and you lose power to the outlets, you may be plugging too many things into the circuit. If nothing turns on when you plug it in, then you may have to reset the breaker.

Breakers are usually labeled with what rooms or appliances they control.

The direction you flip the switch depends on which way the breaker was installed. Always read the labels printed on the switch to know where the “On” and “Off” positions are.

If the breaker still trips once you plug in your devices, you may have a faulty breaker or old wiring that can’t support using all of your electronics. Contact an electrician to help update your home’s electrical system. [9] X Research source

Some homes are wired so multiple rooms are on the same circuit. If you can’t find another GFCI outlet in the room, check any other nearby rooms that share a wall.

Be careful not to hold the hairdryer too close to the wires since you could melt the plastic insulation.

Never handle wires while the breaker is still turned on since you could shock yourself. Check the wires with a non-contact voltage tester after turning off the circuit to make sure the wires aren’t live anymore.

If there are only 2 or 3 wires in the electrical box, then connect the white wire to the silver LINE screw and the black wire to the brass LINE screw. If there’s a bare or green wire, connect it to the green ground terminal screw on the bottom of the outlet. If your electrical box has 2 cables each with 2–3 wires, the wires running back to the breaker connect to the LINE terminal screws at the top of the outlet and the ones carrying power to other GFCI outlets connect to the LOAD terminals on the bottom half of the outlet. Attach the black wires to the brass screws and white wires to silver screws. Then, secure the green or bare wires to the green ground terminal on the bottom of the outlet.

Always check the amp rating and voltage of the old breaker to ensure you get a new breaker that matches it. Take a picture of the breaker’s label so you can easily reference it. Mark the breaker you’re replacing with a piece of painter’s tape since it can be hard to remember which one you’re changing once you remove the cover.
