My new Park Model is rated for 50 amps however the power to my site is only 30 amps. Not a big deal as we did not opt for a washer and drier and use propane for heating, hot water and cooking. I am looking to add a surge protector, specifically a Progressive Industries EMS model. My question, and I have seen various opinions, is whether I should get a 50 amp model to match the unit or a 30 amp model to match the power to the site. I asked this question on their website but never got a response which is a bit concerning as far as customer service goes. I am currently on a seasonal site and I am unlikely to be moving and there is no plan to upgrade the power to the site. While I am at it is anyone else using one of these models and what other surge protectors are people using that they would recommend?
