Thanks for the info. My EMS arrived today, and since the trailer is still at home (did our inaugural trip over the weekend), I'll try and get it installed tonight before bringing it to storage. I have an old dryer cord that should be of large enough gauge to use between the EMS and the breaker box so I won't have to cut the cord.
