Install a water tight outdoor outlet

I use to plug a power cord extension from my kitchen and run it outside to do my front lawn mowing, edging, blower and power washing because it was the closest I could plug into. But recently I decided that I didn't want to keep doing that anymore mind you during Christmas, I have to run a line from inside my living room - under the door type of solution to get power to the lights. Alas! now I can do everything outside the home.


Here's what you'll need:

- Some rust proof screws about 1 - 1 1/2 inch screws, up to you as long as they aren't too short.

Plastic outlet box

Outdoor outlet cover, make sure they are big and roomy in case you have to plug in a fat adapter

Weather resistant outdoor rated GFCI outlet (luckily mine matched my box)

I couldn't find anything shorter but this conduit attaches to the back of the extension box through the brick wall and inside the home, it protects the wires.

First we drill a hole using a concrete drill bit attachment. Hammer drill works best but you can use a regular drill, it just takes longer. The technique is to let the drill to it's job, don't drill too fast or you'll kill your bit (if that does happen, just use grinder to re-sharpen it). Also remember, heat is the enemy, keep your drill bit cool, you can use a water spray bottle while your drilling.

We make our second hole that goes through the wood part - for me it was the floor joist.

We assemble our extension box (unscrew the locking nut, push the flex conduit into it then tighten) then push the flexible conduit through the hole like so.

Mark the 4 holes through the side tabs then drill about an inch.

This would be a good time to wrap the conduit with foam to seal it up. Then screw the box to the siding using galvanized, concrete (blue) or deck screws.


That's about it! the only thing left is to attach the other end of the wires into a junction and your all done.
