This box acts as a third party between the outlet in your wall and whatever high voltage or dangerous project you are doing. For electricity to be flowing to your project from the box you need to be holding down a button, which serves the double purpose of making sure you know when you project is only, so you don't absentmindedly leave it running, and keeping one hand away from any high voltage so it cannot pass through you.
WARNING: This box will not protect you from electrical shock, it will only make sure your project is running only when you want it to.
NEVER have the box open while it is plugged in.
Step 1: The parts
What you will need:
A normally off button (Rated for at least 120v 15 amps)
A Switch (Rated for at least 120v 15 amps)
As many outlets as you want
A power cord
Wire (Rated for at least 120v 15 amps)
Things to hold everything together (screws, bolts, etc...)
A fuse rated around 120v 15 amps
Or you could use a circuit breaker rated for as much as you want it to trip as so you don't trip one on the main grid
Step 3: Get ready to cut
Mark out where you will cut to place all the parts (Ignore that mine looks like a face)
Step 4: Cut all the pieces out
Step 5: Sand the edges and drill the holes
Drill all the holes for the components you will attach.
If you happen to have sandpaper you can sand down the edges of all the holes to make it nicer looking.
Step 6: SCREW EVERYTHING
Screw in all the parts and components!
