Tiny House Electrical System

I finished installing the electrical system of the tiny house.

It consists of a weather proof plug to the outside for a 15A extension cord, a GFCI circuit box, a 15A circuit breaker, 6 switches, 5 outlets (receptacles) and places for 6 lights to be installed once I install the ceiling.

I tested it all too. It was like magic the first time I plugged it in, reset the GFCI and heard the fan turn on. The bath fan is operational too.

The reasoning for the circuit breaker was so that if the occupant overloads the circuit, they can restart it there in the closet rather than having to go find the circuit breaker in the main house or other system. Just unplug something, flip the breaker back on and you’re in business.

Here are some pictures of it. This is the exterior plug at the moment. I’ll go back and put in some foam insulation. You can see the ground wire going up that goes to the trailer frame:

Then this is the GFCI and breaker box. I left the box open here but it will be sealed with a removable cover normally. The entire circuit for the house goes through both of these for safety.

Here’s the bath fan. The light gets plugged in after I install the ceiling. The fan and the light are on the same switch.

Here are one of the two double switches. This one turns on the porch light and the living room and study lights. The other double switch turn on the hall/pantry lights and the closet light.

This picture shows the nailing plates covering the wire, a receptacle and the foam insulation I’m using between the wall and the trailer frame:

And finally… we have light!

That’s one of the LED lights I plan to install in to light up the living room. There are two of those and a few box shaped ones for the hall/pantry, study, porch and closet. I was going to install one in the loft two but opted to leave an outlet and switch up there instead so the occupant can put their favorite lamp there.
