How to Install a 30A Shore Power Inlet in a DIY Camper Van

One of the first electrical projects you should tackle in your DIY Camper van build is installing the 30A shore power inlet. Since the 30A shore power inlet needs to be installed in the side of the van (traditionally), it’s best to do that before the walls go up and before you start insulating.

This blog post will walk you through installing a 30A shore power inlet into the side of a DIY camper van and connecting the 10 AWG Triplex wire to the inlet. We will not be connecting the other end of the wire to anything in this tutorial as that will be covered in an upcoming ‘How to Wire a Victron Multiplus Inverter/Charger’ blog post.

Choose Shore Power Location

We are going to install the Battle Born Battery bank and other related power equipment over the drivers side wheel well of this van, so we will be installing the shore power inlet on the other side of this wall back here on the rear quarter panel.

Remove Inner body panel

We needed to gain access to the inside of the rear quarter panel so we removed the factory installed panel by using a trim clip removal tool and working our way around the panel removing the trim clips so we could get the panel out of the way.

Protect Shore Power Location w/ Painters Tape

To protect the outside of the van from any kind of metal shavings, we covered the entire area with painters tape.

Drill Pilot Hole from Inside of Van

Then we drilled an 1/8th inch hole from the inside of the van with our cordless drill.  We duct taped our shop vac nozzle to the inside of the van to be sure to catch all of the metal shavings.  We drilled this hole from the inside so that we could be sure to give ourselves plenty of space from any of the body support ribs or any other obstructions inside the van.

Tape Box on Outside of Van to Catch Metal Shavings

Then we moved outside and taped a box around where we will be using our hole saw to further control any metal shavings.  If you’re not picking up on it yet…  metal shavings are bad… They always seem to find their way into the most inconvenient spots and promote rusting.

Use a Hole Saw to Cut the Shore Power Inlet Hole

Next is hole saw time.  We used a 2 and 7/8ths inch hole saw and VERY CAREFULLY started cutting our hole from the outside of the van.  The metal of the van here is INCREDIBLY thin, so this doesn’t take very long.  We didn’t use cutting fluid as this cut shouldn’t take long enough for the blade to heat up and it wasn’t worth the added mess.

Mark Screw Holes for Shore Power Inlet

Now that our hole is drilled, we are going to take our shore power inlet and put it into the hole and line it up so it’s nice and level and then use our drill to lightly mark where the holes need to be in the van body.  A mechanical pencil with some long lead or something would have worked better here; but alas… we didn’t have one.

Drill Screw Holes

Next we used an eighth inch drill bit to drill the 4 screw holes…

Deburr Shore Power Inlet Hole

…and then a deburring tool around the bigger hole to get rid of any sharp parts or edges.

Treat Unfinished Edges with Paint to Prevent Rust

With all edges cleaned up, we held a piece of cardboard over the back of the hole and then sprayed a bit of rustoleum paint over the area we’ve been working on to cover up any exposed metal to prevent it from rusting.  Then we did the same on the back side.  We didn’t tape off the back since all of this will be covered up with insulation and walls, so we weren’t too worried about it.

Remove Tape and Clean Shore Power Inlet Area

Now that we were done making metal shavings, we could remove the box and tape from the quarter panel and carefully give the area, both front and back, a once over with the shop vac brush attachment.

Remove Shore Power Inlet Retaining Clip & Insert Wire

Next up we can wire the shore power inlet, so we’re going to remove the retaining clip on the back of the shore power inlet and then feed the 10/3 wire from the EXPLORIST.life 30A Shore power wiring kit through the back cover of the inlet.

Strip the Insulation from the 10/3 Wire

Next, we’re going to strip the outer sheathing back about 2 and a half inches and then strip 3/4 of an inch off of the end of each wire. Ferrules don’t fit particularly well in this shore power inlet, so we aren’t going to use them here.

Loosen Wire Terminals on Back of Shore Power Inlet

Next we are going to loosen the wire retaining screws on the sides of the shore power inlet.

Insert the Wires into the Back of the Shore Power Inlet

Insert the Black, White, and Green wires into their respective color coded holes.

Re-tighten the Wire Terminals on the Back of the Shore Power Inlet

and then re-tighten the wire retaining screws to 20 inch lbs of torque making sure there is no insulation under any of the terminals creating a poor connection.

Put Shore Power Inlet Housing in Place

Then we can slide the shore power inlet rear housing up the wire and then put the retaining clip back back in place.

Fasten Shore Power Inlet to the Van

Next we are going to fasten the inlet to the van by placing the inlet in place, putting our 1 inch #8 stainless steel pan head screws into place, and then threading our washers and nylock nuts on the back and tightening them until they are snug.

Waterproof Gasket Already Installed

The back of this inlet has a waterproof gasket pre-installed on it, so no additional sealant should be necessary; but if you are mirroring this installation and don’t trust the seal, feel free to add a bead of dicor sealant around the perimeter.

Coil Wire & Save Ferrules for Later

The ferrules that were included in the wiring kit from this installation will go on the opposite side of this wire when we wire this inlet to the Victron Multiplus Inverter Charger later in this series, so I’m just going to tape this baggie to the end of this wire and coil the wire up for safekeeping for later.

Installing a Shore Power Inlet in a DIY Camper Van – Finish

And that’s all there is to it!  The shore power inlet is now installed and could technically be connected to a 30A shore power inlet at a campground or to a standard 15A household outlet by means of a 30A to 15A adapter… but don’t connect that yet…  remember… The other end of the wire in the camper is not connected to anything so we don’t want to send power to it.

Now that we have the shore power inlet installed in the side of the van, it’s time to move on to the next step in this series.  We need to remove the headliner of the van to start making access to as much of the metal of the van as we can so we can start getting our plan together for sound deadening and insulation…and that’s coming up next.
