Why would you need a commercial electrician?
If you need electrical work done in your business premises, you’ll need a commercial electrician. Commercial electricians might plan and diagram electrical systems, and they often work from blueprints provided to them by a general contractor.
Commercial electricians will install electrical wiring according to blueprints, terminating them at switches, circuit breaker panels and relays. They may also wire up instruments that control power, lighting, heating and air conditioning.
