AZ DIY Guy's Scary Warning - Electrical Edition
Don't mess with electrical, unless you know what you are doing.
When in doubt, get a professional electrician. If you do these residential projects are a snap for someone who's trained; it shouldn't cost too much.
Even if you know what you are doing, I recommend you work it like it's live, even if it's not.
Research legal requirements in your area before making changes to your electrical system.
