I am rewiring my house after a copper theft, and have a few questions about what's legal and what isn't.
I bought a great book from Home Depot that gives a simplified explanation of the NEC, but there are some items missing.
In the breaker panel, there are holes into which romex clamps allow wires to be passed into the panel. I believe the proper name is 'clamp connector for NM cable'. I need to know if it's ok to run as many wires as the clamp allows (physically), or whether the number of wires/cables is limited?
Also, some NM type cables are run through holes in the floor joists. Am I allowed to run many cables through the same hole, or is there a limit to the number of cables that can be run through a single hole?
Can multiple romex cables be secured by the same staple, or must there only be one cable per staple??? I am aware that I can't bundle or enclose the cable run without de-rating the current rating of the cables.
Also, I need to know if insulated staples must be used or whether I can buy the much cheaper standard type?
Please note, I am (obviously) not an electrician. I would very much like to hire an electrician to do the job, but our home insurance is not covering the copper theft, so I am forced to do my own wiring-nearly 100 percent of the copper cables were stolen by the thieves. I have some knowledge of electronics, but no formal electricians training.
Thanks,
T
