Electrical Codes and House Trailer Wiring

• Romex Type NM Cable
  I was involved in a relocation project where the military was relocating service personnel and their families to mobile home parks and I recall that the electrical wiring for two modular sections was spliced under the home into metal junction boxes.
• The wiring was Romex Type NM Cable which was installed above the membrane fabric, and this was acceptable in the state code here in California.
• Installing and Supporting Electrical Wiring
• This is very similar to installing electrical wiring under a conventional home where the wiring is well supported and secured to the floor.
• Be sure to consult your local building department for verifications and details.
