A commercial electrician may also use an infrared thermometer to find out if there are hot spots in the building, such as a hidden short circuit that’s overheating and melting something like plastic or rubber insulation on the wire. This is done by pointing an IR thermometer at different areas in the commercial building and checking for any hot spots. The commercial electrician will use their knowledge of electrical theory to figure out what needs to be done, whether it is replacing a circuit breaker or repairing damaged wiring. Commercial electricians must also follow safety precautions when doing this type of work because electricity can pose a serious risk if handled improperly.
Electrical Panel Inspection Procedure
The commercial electrician must first visually inspect the electrical panel to see if there are any obvious problems like loose connections or breakers that have been tripped off. Then they will check for voltage on all breaker boxes by using a commercial multimeter and making sure it matches up with how much electricity is being used at that moment in time. They’ll also make sure that all of the breakers are on and working properly, as well as checking for any power quality issues such a surge or spikes.
Next, commercial electricians will use an IR thermometer to check if there are hot spots in the commercial building caused by hidden short circuits or overheating which is melting something like plastic or rubber insulation. If commercial electricians find hidden short circuits, they’ll need to fix the problem by repairing damaged wiring or replacing a circuit breaker that may be overloaded.
5 Types Of Electrical Repairs
Commercial electricians will work on any of these five types of commercial electrical repairs:
Replacing a circuit breaker
This can be done by using a commercial electrician’s multimeter to check for voltage or current in order to make sure that there are no short circuits before turning off power. Commercial electricians also have to follow safety precautions when doing this type of work because electricity can pose a serious risk if handled improperly.
Rewiring commercial electrical panels
Usually involves removing the old wires and then installing new ones with connections that commercial electricians have previously checked for voltage or current before turning off power.
Repairing damaged wiring on commercial buildings
Commercial electricians will repair damaged wiring they find with their infrared thermometers.
Fixing commercial electrical panels
Commercial electricians may find damaged electrical panels during the inspection process, which commercial electricians may do if they’re not sure what’s wrong or in case of an emergency. Commercial electricians must first understand how to read and identify different types of breakers before fixing commercial electrical panels.
Replacing commercial electric plugs and outlets
This usually involves installing new ones with connections that commercial electricians have previously checked for voltage or current before turning off power. Commercial electrician must first turn off power to the building’s circuit breaker panel by flipping breakers on one at a time until the desired circuit is found.
