Humidifier MCA / MOP
(OP)
Im trying to determine the correct MOP for a commerical humidifier. The unit is 51kW. If i go by my standard motor calculations by the tables in the CEC i get an MCA 77Amps and MOP 175Amps. Is a humidifer calculated differently than a regular motor?

Now assume that the motor is 1 kW and the heater coils are 50 kW. Calculate your wire size and protection required.
Compare the results.
Either RTFM or call the manufacturer.

We can only engineer what we know. Transformer are built to known standards and we know what is in it. A humidifier is not a standard equipment. What is a "straight" humidifier? Humidifiers consist of multiple components, (heaters and motors etc,) which varies by the type of humidifying technology (infra red, ultrasonic, steam, etc.)and manufacturers. Engineers are not magicians or mind readers. Learn to obtain the data you need to do your work.

rb: You're answers are very patronizing. The idea of being on this forum is to help people not attempt to give lectures. I wish I knew everything like you do so I wouldnt have to ask questions.
Im not sure where you work but in my position we rarely have all available information and its frequently completely unavailable. I was merely looking for a general rule, which aparently there is none, which is the answer I was looking for.

You are not getting the message. There are no rules for unknown quantities. You need to find out what is in the humidifier you are interested in or being specified. It is not knowing about everything, it is knowing where and how to find answers. You are not going about it the right way.
