Canada's Number One Circuit Breaker Specialist

Testing

We back up our breaker testing with written test results, an insurance policy for you.

Think of tested breakers as an insurance policy for you, your customers and your business. When it comes to the installation of circuit breakers your company takes on an enormous liability if you install circuit breakers that are untested or have no documentation to back it up.

Eliminate unnecessary risk

All testing is performed by Certified Low Voltage Circuit Breaker Technicians.

Our testing standards meet and/or exceed testing standards set out by  PEARL, NEMA, NETA , IEEE and even the manufacturers testing standards.

We are the #1 new/used circuit breaker dealer in Canada. We stand behind everything we sell, new and used with our 1 year 100% guarantee.

The reconditioned breakers we sell come with a unique tracking number that corresponds to the test report that goes with your breaker.

Fully Reconditioned and Tested Circuit Breakers

Breakers are first cleaned inside and out then undergo a step by step 36 point visual inspection of the exterior and interior (see below). Next, comes the actual breaker testing. Molded case circuit breakers consist of three major components, the insulation, contacts and the trip unit.

Three different pieces of equipment are required in order to fully test a breaker and determine that it is safe, reliable and trips according to the manufacturer’s own trip curve.

1. Insulation Resistance

This test is necessary to verify the condition of the breaker’s insulating materials. Testing is performed using an insulation resistance test set at 1KV. All results are recorded in the test report.

2. Contact Resistance

This test verifies the current path in the breaker. Loose or bad connections, dirty hinge points or contacts, and burnt contacts will all show up as a high resistance reading. Testing is performed on each phase individually using a digital low resistance ohmmeter at 10amps, results are measured in milliohms and recorded in the test report.

3. Over current Trip Test

This test is to verify the time-current characteristics of the breaker. Testing is performed with direct injection to simulate an overload current. We have assembled over 2000 manufacturer’s trip curves and test each phase on every molded case circuit breaker to ensure that it trips according to the manufacturer’s very own factory specifications.
