Commercial wiring help

[jrz126]

I started working at a small lighting company a few months ago. I've been put in charge of creating wiring diagrams. Most of the diagrams are already done, so I basically just need to tweak them for the different light options. No one here is really familar with the electrical codes, so I dont know if they are being wired properly.

The attached diagram shows the wires that come out of the fixture for a 3 circuit light. Should there be a seperate neutral and ground for all 3 circuits?

Is there a book or anything that I could read to get up to speed on wiring?

These lights are specifically made for hospitals if it matters.

That's scary!

The city you are performing the work in should have an electrical code book loaded with standards and regulations available to contractors. Also, the county will probably have one, the state will and the entire country has.

Click here to go to NEMA's website.

now is these lights stand alone lights(such as on placed on a desk with a control circuit inside of it)or are they built in permanent fixtures? If they're permanent fixtures in the building then you need to consult the NEC code and contact a electrician. If it stand along units then consult NEMA

Good point!

Sounds pretty typical to me. Far far to often I here that
'I'm a licensed contractor/electrician or work for a licensed manufacture therefor I dont need to know the codes.' Reasoning.

I hope your company is not one of them but I suspect it already is.
