How to install a mains hook up inlet socket in your van

1. Choose a bi-metal holesaw that fits your mains hook up inlet socket

  • Choose a hole saw that fits the mains hook up inlet socket perfectly (as flush as possible)

  • You will be cutting a hole in the sidse with this hole saw and its important it doesn't overlap the mains hook up inlet socket!

2. Place the holesaw on the side and trace it with a pencil

3. Drill a pilot hole in the middle of the traced circle and two more pilot holes close by on either side

4. Tape a piece of scrap wood to the side of the van to cover the three holes you just drilled

5. Screw into the piece of plywood from the outside to secure it to the van.

6. Attach the hole saw to your drill and drill into the van

  • N.B: We attached the plywood to the van to prevent the holesaw from wandering when we use it - they can be a little tricky to use in thin metal.

7. Apply metal paint to the exposed metal to prevent rust

  • Ensure you also clean all the metal shavings (swarf) off your van. If you don't you will have a lot of problems with rust in the future - they corrode quickly.

8. Place the mains hook up inlet socket in the hole you've just cut and mark with a pencil where the screws go in

9. Drill pilot holes on the pencil marks

10. Stick the scrapwood onto the inside of the van with Sikaflex

  • This will be the backing flange of the mains electrical plug inlet

  • Clamp the scrapwood to the van until the Sikaflex has dried and secured

11. Screw the electrical plug inlet into the van from the outside!

12. Apply sealant around the inlet to prevent any leaks!

And that's it! There are a few steps, but it's really quite easy.

Beware of the following when using a hole saw (N.B!!):

  • Use LOTS of oil on the metal you are cutting (WD40 will do) - you will destroy the hole saw if you don't

  • Use the drill on a low RPM (rotations per minute) - you will destroy the hole saw if you don't. This means that you shouldn't press your finger all the way down on the trigger of the drill

  • Pulsate the drill while you are cutting - you will destroy the hole saw if you don't. Use a stop and start motion while drilling, this gives the holes saw a chance to cool down (it gets very hot)

Learn from my mistakes; I bought a very expensive bi-metal holesaw and destroyed it within 5 minutes because I didn't follow the advice above.

Careful of the swarf:

  • When using mechanical tools on metal, a lot of metal shavings are produced ( known as 'swarf'). It is vital that you remove all these shavings from the van when you are finished, if you don't they will very quickly rust and damage your vehicle. They are quite sharp, so be careful when handling them.

  • Always wear goggle while using mechanical tools on metal; if swarf gets into your eye, it could have very serious consequences. You should also wear earmuffs - these tools are VERY loud!
