When there is an electrical problem in residential or commercial properties, the process is about the same. It is a step-by-step process. Electricians must troubleshoot electrical issues in a step-by-step manner to safely and efficiently eliminate the problem. Below are some ways electricians troubleshoot some common problems in the home and commercial buildings: Residential Troubleshooting:

Power Outage: Power outage is the result of tripped circuit breakers, faulty wiring, loose wire connection, or any other problem with the connection of power to the main source. The electrician generally checks the connection to the circuit panel.
flickering lights: the causes of flickering lights may be due to loose connections, faulty wiring, or overloaded circuit connections. Generally, electricians inspect wires and circuit connections for abnormal conditions.
Non-operational outlets can be either due to bad outlets, faulty wiring, bad GFCI, or tripped breaker. Electricians usually check the breaker, the outlet itself, and sometimes the wiring.

Commercial Troubleshooting:
Restaurants: The loss of power or flickering lights in restaurants may be due to overloads and faulty wiring in your kitchen equipment. Usually electricians check the load on your circuits and make sure that cooking equipment is operational.
-offices: any dead outlets, power surges, or flickering lights during the daily operations can hinder effective operation. Electricians can troubleshoot the issues with the circuits, wiring, and/or bad equipment causing your problems.
