Hi Guys,

Are we now required to use sch 80 pvc conduit for mobile home feeders. I had an engineer the other day tell a customer of mine that the pvc on the exisiting service had to be changed to sch 80. And on the flip side of that he had stated that the exisiting 4/0 quaduplex RHW Aul was OK. Frome my understaing we now and for some time had to us RHW-2 wire on mobile home feeders. Another thing, he also stated that iI had to have a clamp on wire entering two of my metal boxes. I have it stapled within 12 inches of each box. Hum, whats wrong. Bill or anyone have any input on this.

Probably what you are seeing is local requirements above those of Art. 550 and maybe Art. 552 (Park trailers). Most of the counties here require a pole within a few feet of the mobile home with the meter and a panelboard mounted on it with at least a 100 amp breaker to serve as a disconnect outside in case of fire. Schedule 40 PVC was Ok a few years ago when I installed one. That may have changed recently. If I had to install another, I would check the local requirements.
Park trailers are limited to 400 sq. ft. Thats a 10X40 mobile home. Many travel trailers are that size and larger set up in parks. Local ordinances would probably dictate more stringent requirements than in the NEC.
