Stage 6a – First Fix Electrics 12V

For all the lighting we will be using 12v 14 Strand cable

We are going to have 5 ceiling lights, 2 in the front, 2 in the rear and 1 in the bathroom. To achieve we have run 3 separate feeds from the Sargent unit out to these 3 separate sections. We will also have some down lighters in the under the lockers and above the kitchen unit, plus some additional decorative DOT LED's in the kickers of the seating area. We will therefore run 1 feed for all the down lights and 1 feed for the decorative DOT LED's so we can isolate these if required.

Therefore we have 5 separate runs from the Sargent unit to all the lights. The back ceiling lights we have run 1 cable to the first light, leave a loop, the run it to the second light and finish at that second light. (No need to return back to the unit as the cable is twin cable)

We repeat this again for the front lights

The same process applies to all the down lighters, run the cable to the first light, loop the cable at this light, run the next light and leave a loop and so on, finally finishing at the last light

This wires in very much the same way as the lighting, the only major difference is the size of the cable. It needs to be bigger cable as the draw on 12v sockets can be larger that lighting. Therefore we are using 12v 28 Strand cable for this, the plan is to have 4 x separate 12v sockets located around the van, because of the location of them we have decided to run them on 3 separate feeds form the Sargent unit.

We have 1 near the kitchen wall, 1 in the side of the kitchen unit accessible form the end of the kitchen unit near the sliding door, so we take the 28 strand cable form the sargent unit, loop it at the first socket and then finish at the second socket

The other 2 sockets are on the opposite side of the van and as they are far apart we are running these on separate feeds (Also as the feed for the 12v sockets is constantly live we will be using this same feed for some 12v items near by - See below)

The Sargent units have a dedicated connection for the pressure pumps so we will run a separate feed from the sargent unit to the pump using 12V 28 Strand cable.

We are using a 12v flush toilet so this needs a 12v live feed, as there is a 12v socket close to the shower room we can use this feed to connect the toilet form the same cable

As with the above toilet there will be a 12v socket near by, we will therefore use this feed to connect the 12v on the water heater

Again there is a 12v socket near by the cooker so we can use this feed for the ignition on the cooker
