How Often Should Commercial Electrical Installations Be Tested?

It’s important that all electrical wiring and installations be checked on a consistent schedule to ensure that your commercial property is protected against possible electrical fires, faults, or other damages.


How often should commercial electrical installations be tested, and exactly what does an electrical inspection entail? We’re here to take the guesswork out of your commercial electrical maintenance.

How Often Should Commercial Electrical Installations Be Tested?

Commercial electrical wiring should be tested every 1 to 5 years depending on the type of business operating on the property. Electrical inspections can be scheduled as a 100 percent inspection once every 5 years or a 20 percent inspection scheduled annually, rotating between sections of your equipment during each inspection. In either case, all electrical installations should be tested at least once every 5 years. Be sure to keep a detailed record of what has been checked and on what date.

What Does an Electrical Inspection Entail?

Overall, periodic testing helps pinpoint any type of defective electrical installation in your commercial property so you know to get it properly repaired.

Periodic inspections and testing of commercial electrical installations include checking your property for any faults that would indicate overheating circuits or circuits that are overloading during use. If an electrical circuit was installed incorrectly, such as one without the proper bonding or one that became loose over time, it could present a safety hazard to your commercial property. Regular commercial electrical inspections help identify these types of issues so you can avoid damages and keep your building occupants safe. 

In addition to checking for faults, your electrical technician will conduct a thorough visual check for broken light switches, blown sockets, scorch marks, bad wiring—anything that looks out of place.

Schedule Your Commercial Electrical Inspection

Once your inspection is complete, your technician should provide you with a certificate to report everything that was completed during the inspection. This Electrical Inspection Condition Report (EICR) will outline any and all damages, defective parts, and deterioration so you can get the proper repairs needed to meet current safety standards.
