My RV is hooked up to a 50 amp electrical supply with one breaker at an RV Park. All electrical appliances seemed to be operating OK. I purchased a progressive model SSP-50 RV Smart Surge Protector. Upon hooking the surge protector up to the electrical supply without the RV connected I saw red lights that indicate an open ground. What are the potential problems by using the electrical hook up and what could be wrong.
Thanks for your help.
