I have a Hobart P660 stand mixer. It turns on for a moment then trips the breaker. Would this be a "relay" or "switch" problem?

Sounds like the cable is too small. If you're hooking it up to 15 amp breaker you need the correct diameter size extension cord, and the equipment cannot be rated more than 15 amp or you'll have a problem. I perceive this may be the solution based on the fact that you said that the motor was not coming up to speed.

the whole mixer is running backwards, change any two wires on the 3 phase power going into mixer.

A good standard 90 wt oil is what is ok for the gearcase. This is an old email from a hobart service tech and they recomend a special oil ordered from them. So you can decide which you want to use. "EXXON SPARTAN EP-150 (6 oz)" in the M802 planetary. Hobart part #102973-13. This IS NOT a food grade oil. If you mixer is leaking you shouldhave it serviced. Service, parts , lubricants and information canbe obtained by contacting your local Hobartoffice in Pittsburgh@ (412) 788-5380. Steve Davis Field Engineer -

If you do not have a bowl guard then it is most likely the side switch on the contactor. If you have a bowl guard, it could be the bowl height switch or the contactor side switch. Make sure there are no loose wire connections before you replace parts. The bowl height switch may just need adjustment.

Good!

the elec. schamatic for the p-660 should be inside the top cover of the mixer, that mixer was specifically built for s'barros pizzerias

I personally would not do it.
