Mechanical load, wrong overload setting, lost phase or low voltage — how to tell which one you have before you reset it again.
Plain explanations of the equipment faults that come up most often on service calls around Red Deer. Read the one that matches your symptom and you will know more before the truck arrives.
Most calls start the same way. Something stopped running, somebody pushed reset, it ran for a while, and then it stopped again. These pages work through the usual reasons that happens — in the order those reasons actually turn up on a shop floor, a farm yard or a commercial building — so you can describe the problem accurately, rule out the simple things, and know when it is time to isolate the equipment and stop.
They are written by Todd Grasse, a Red Seal Journeyman Electrician and the owner of Grasse Electric, based on work done across Central Alberta since 2018. There is no attempt here to talk anyone into work they do not need, and there is no attempt to walk an untrained person through live troubleshooting. Where a step means opening an enclosure or taking a reading on energized equipment, the guide says so and stops.
Anything involving permits, code compliance or an inspection outcome should be confirmed against the current Canadian Electrical Code as adopted in Alberta and with the authority having jurisdiction for your location. The guides describe requirements in plain terms rather than quoting rule numbers.
Mechanical load, wrong overload setting, lost phase or low voltage — how to tell which one you have before you reset it again.
Acceleration time, shorted output, motor problems and parameter mismatches, and what the fault code is really telling you.
Phase rotation, what changed, and why swapping leads at the wrong point can cost you more than it fixes.
Control voltage sag, interlocks, worn contacts and coil problems — chattering and dropout have different causes.
Single phasing, where it usually originates, what it does to a motor, and why it needs to be found rather than reset.
Overload, short circuit, ground fault or a tired breaker — how the way it trips narrows the cause down.
Drivers, heat, voltage, surges and control wiring — why the same fixture position often fails twice.
You can use them to narrow down the problem, describe the symptom properly and check the things that do not require opening an enclosure. Anything past that — readings on live conductors, work inside a panel or starter, replacing electrical components — is work for a qualified electrician.

Usually. If you can tell us the equipment, the nameplate details, what the fault display says and whether it fails on start or after running, the first hour of the call gets spent fixing rather than gathering information.
Some. The work here is mostly commercial, light-industrial and agricultural, with selected residential and shop and garage work. The breaker and lighting guides apply in most settings.

Send the nameplate and the fault display with your request and the call starts ahead.
