Calculating Motor Overloads

This video walks through the steps to calculate the maximum overload setting for an individual motor using the 2015 Canadian Electrical Code. This is not an installation guide, and local inspection authorities should always be consulted.

Feel like buying Chris a coffee? Think of it as SchulerRuler fueler!

Over ten years in the industry and your video just cleared many unanswered questions. I like your method of explaining. thank you.

Appreciate the refresh. All journeymen/women should take some time to review their knowledge base. The field is so diverse and its easy to get stuck doing the same things for a while, which leads to important aspects being forgotten.

Congrats on the channel.

I don’t know where will I need this info but you are a good teacher sir 😀

[angusandleigh]

...Excellent video, I've been trying to explain this simply for my road techs...this is the BEST explanation I've found....Cheers man.

This was SO helpful for the program I am doing! Thanks for the great class!

[nogarats]

Great class, very good explanation and well paused. appreciated !

[williansousa]

Great class! Thank you. It helped me a lot for preparing to take my challenge exam.

You teach so well. I'll try to support through views and likes. Thanks for making informative videos likr this. 👏😃

[revertedakhi]

Excellent explanation! Your explanation is clearer than my future JK hehe nice video.

wait, how the hell can you write backwards so flawlessly

I'm trying to calculate an ISO or German motor with a cosine of 0, 95 ~ My understanding is that "european" motors are basically at factors of 1 on down to 0.85 or so which isn't very efficient. So if the motorplate says AMPS at 3.4 ~ with a cosin of 0.95 I would set my overload "at basically" 3.4 Amps IS THIS CORRECT?

Great vid. Can u explain difference between HOT state and COLD state of a thermal overload relay, thanx

Hello Sir Thanks for your videos, found really helpful.
I need electrical codes book ?

[matthewmacpherson]

Studying to challenge my third block and these videos are so helpful. If you have any tips for third year code, I would be beyond grateful. Thanks for doing these!

you should do welders section 42 calculations in there

If I have A 30 HP, 600 V, 3 Phase squirrel cage motor feed from autotransformer and is controlled by a Star-Delta starter. What is the maximum size inverse time circuit breaker allowed to protect the circuit.
Is it based on phase current like the above video showing?

[karimeldaly]

@schulerruler Hi. In case of Y/delta motor, the overload relay will be installed after the main contactor?

[thekhang]

Why Y/ ∆ start using phase current, while other motor using line current ( FLA )???

[roseandmose]

Can you suggest some sources me to learn basic of these terms
