I recently bought my first class A. A 2008 bounder 35H. It is also my first experience with a 50 amp system as well as a 5500 watt onan generator. I was wondering if the automated electrical control system in this coach has a built in surge protector or if it would be advisable to add one to the shore power cable?

I consider it a necessary addition if there is not one already. Mine is a Progressive Ind. hard wired unit that has saved me a few times from high as well as low voltage readings.

IMO, get the best: Progressive Industries 50AMP EMS. (I say "best" because I have one...the portable unit).For years, I never needed one....then a nearby lightening strike fried my fridge and damaged my transfer switch. $1400.Researched a bit, found Progressive Industries...50AMP..comes portable or hard wired. I think I paid around $350 for it. Better than another $1400, yes?Also, Progressive gives a lifetime warranty. The ones from Camping World do not. ((Get the EMS...not just the surge protector.))Bought it on-line from Tweetys. At the time, they had the best price.

Definitely get PI EMS unit. It gives the best protection. One in our park lost his electronics because of an underground electrical fault between two pedestals and didn't have an EMS. By all means get one.

Secondly, no one is "giving" you anything - you pay for that warranty within the price of the unit which is higher than a comparable TRC model.

There are "Surge protectors" and there are SURGE PROTECTORS!!!I have both. the first protects against only one thign (Spikes in the voltage short term transisent spikes that can easily hit 1000 volts often happen when an A/C kicks in or out)The other SURGE GUARD protects against high voltage (Surge) Low (Dip or brown out) some do off frequency, Open neutral 240 volt 30 amp outlets and more. Progressive Insudtries makes both types but the HW 50/30c are the best (the 50 ois for 50 amp rigs. you can figure out the 30)
