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.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
