Air compressor blows breaker.

[river-rat4]

The tag on the side says:

115 Volt

6 HP

15 Amp

Doesnt say anything about a max breaker size.

And it is a 30 gallon.

6HP? No such thing. 15amp, 1 to 1/12 HP max runs on 15amp breaker.

A "True" 5 HP motor draws 22amps, 220/230volt, single phase.

Compressor MFG's play games. "Peak" hp is the killer. Motors are rated at "Peak hp, No load, at start up". (Rated at 4 times the name plate, from dead stop to start(the reason a breaker will not trip is it is time delay, amps are huge for a millasecond to start the motor)) I am speaking of the "big box store compressors" (and vacuums). Ha, wife has a 12 hp Hoover...(Max single phase,230 volt hp motor can run is 10hp, she runs it on a 15 amp 110 volt shared circut with the microwave, and kitchen lights...

Ratings in compressors are not spot on.

Brandt, how you been.

I was hoping you'd find this thread.

I figured the same thing on the 6 hp rating.

Brandt is a compressor guru btw.

So whats your take on the tripping breaker?

Sorry I forgot to add, it is a 6hp peak and 1 1/2hp the rest of the time.
