Plugged in and Generator
New to Class A and wondering a couple of basic questions: Will it hurt anything if I'm plugged into shore power and then start the generator? Same question but if I start the coach...

With Transfer switches, it is NEVER a good idea to transfer power under any load. Regardless of Shore Power or Genset. The reason is, there are contac points in a transfer switch and transferring under load will cause those points to arc and slowly build up deposits on those points until one day they fail to make contac even tho they close. The best way to transfer is to turn the MAIN breaker OFF at your inside Breaker panel and then either connect to Shore or allow the Genset to transfer, then turn the breakers ON. There is NO system out there that if wired to code will cause a problem (hazard), by turning the genset on when connected to shore power. Or Vice/Versa. Doug
When I attended an Onan Generator seminar a couple of years ago, they were very insistant about NOT starting the generator while plugged into shore power and not plugging into shore power while on generator power.
That is just a CYA statement. I have probably started Gensets on thousands of Motorhomes with shore plugged in in the past 37 years. It IS a good practice, but I doubt that less than 1 percent of RVers ever do it. Doug
