Deb, your probably right about my knowledge about "stationary air compressors", so to test your theory, I always accept a challenge to learn more, and I went out to learn how these air compressors really get rated.
That is what makes an electrician better, and try not to make the same mistake twice. I really strive to give good, accurate, and safe advice. I truly hate people getting hurt and fires burning down buildings.
I also apologize for my flippant comment about making money installing circuits that were too large for an unsuspecting customers. I really don't do that in my everyday business. I truly try to be consultative and do no more and no less than needed.
If I had been given the job connecting your unit, based on your information, if I did not do due diligence, this may have occurred.
I do know that stationary means just that, it is intended to remain in one place, as opposed to the opposite of portable, so lets move onto air compressors of your style.
I did not know that the HP rating was for the pump, never heard that before. HP in electric appliances was always for the motor, so I automatically went there, that's all electricians usually know, at least this one.
And keep in mind, I am not trying to impress myself with how smart I am. I did that years ago. That was not the context in my trying to answer your question.
I came across some interesting information that you may find helpful in making a decision in purchasing an air compressor.
Seems DeVilbiss Air Power Company was one of
several plaintiffs listed in
several Class Action Suits, along with some other popular AC makers accused of misleading of consumers regarding the "Peak HP ratings of small air compressors.:
Campbell Hausfeld
Ingersoll-Rand Company, Ltd.
Coleman PowerMate, Inc.
I found this at:
Campbell Hausfeld Devilbiss Air Power Ingersoll Rand Coleman Powermate Inc Lawsuit Attorney | Lawyer Air Compressor Manufacturers Settle Underpowered Motor Action for $40.6 Million
There is quite a list of brand names involved, along with various settlements to correct advertised ratings.
This information was corroborated and confirmed at several other websites:
Excerpt from:
Evaluating True Horsepower and CFM Ratings of Air Compressors
Air compressors for the home or small shop have been advertised and sold with
ridiculously inflated horsepower ratings.
And
Excerpt from:
Air Compressor Buyer's Guide
Horsepower rating really matter?
The answer is no.
When an air compressor is built, it requires a motor or engine to power the process of producing air. The horsepower is not the only component of the equation. It has to be combined with the compressor pump that it runs to produce the air needed. The bigger the horsepower does not necessarily mean more air. Remember to keep your required
cfm in mind. Horsepower does not make you work more efficiently, but horsepower working in unison with a quality pump that produces enough cfm for your needs.
BEWARE: Make sure when shopping that you look for the running horsepower and not the peak horsepower you get at startup. Some manufacturers have falsely advertised or implied the peak horsepower to be the normal run horsepower. At start-up, there is a surge of power needed to start the motor and can be 1.5-3 times the amount of running power needed. This means the horsepower need for the motor peaks as well, but then drops back down to normal. Many of these manufacturers are involved in a class-action lawsuit for misrepresentation. They have used man’s machismo of “the more horsepower, the better” to their advantage to make sales. These aren’t cars we’re talking about!
Just to name a couple.
So, I hope I helped to change your opinion of the intent of my advice.
If anything, you certainly helped me, and even better, any other readers of this post, in understanding air compressor ratings.
Oh, but wait a minute, you already bought one of these.
Change Buyer Beware to Owner Beware.
