Large Jacob's Ladder

Step 3 Transformer

Most transformers don't come with a wall plug, so you'll need to wire on in. Don't worry though, it is really easy. All you have to do is get a wall cord (I got mine at Home Depot) and attach it. Black goes to hot, white goes to neutral, and green goes to ground.
Make sure to ground your transformer!
Once it's wired, attach 18" of the 14 gauge wire to each output and strip the ends.
