The Manufactured Housing Forums

I am preparing to install an electric water heater in my mobile home, it currently has a 30 gal electric W/ Dbl pole 25 amp breaker I intend to replace it with a 50 gal if room allows otherwise I will go for a 40 gal my question is about wiring it up someone at a hardware store told me they had to be wired differently? I was never aware of this is it true? I am aware that the electric range pigtail had to be wired differently when installing it because I had to wire one before my question is was the clerk just being a jerk as many are towards mobile homeowners? Any answers will be appreciated thanks~~~Alien
