I have to agree with Darkbird here. Anytime a company is dealing in any type of electrical components and moisture , they have to tell you to have it GFCI protected. if they didnt they would be opening themselves up for a lawsuit. I will say this, after being in the building trades for almost 20 years , it is never a bad idea to plug a gfci inline of a rhp. consider it an insurance policy. Now in the real world I own 7 Pro Products RHP's and none of them are connected to a GFCI. I have been running them for almost 1 1/2 years in humidity as high as 80% during sheds and neither I nor my animals have had issues of being electrocuted. By all means contact Bob at pro products and see what he has to say . He is a great guy to chat with! Best of luck with your new RHP ( i think you are gonna love it
