Really basic quesitons about wiring florescents in continuous row

[snorky18]

I've done a lot of electrical work, but I've never wired florescent fixtures in a continuous row before.

I know that the fixtures have to be rated for continuous row wiring. Mine are.

Is the entire fixture basically considered a giant junction box / raceway?

What type of wire should I use between the fixtures? NM, or just plain THHN cable?

I'm assuming each fixture needs to be grounded individually?

Are the basic steps basically bring power into the first fixture through a KO, connect the ballast along with another set of wires to run down to the next fixture, and rinse, lather, repeat till you get to the end of the row?

Yep that fixture is one big box. In our area of the country you need a quick disconnect on the power wires. THHN is fine. Consider running two circuits or one 220 and switch every other fixture. That way if you don't need all that light just turn on one circuit.

No one locally sells THHN by the foot, except for home depot who mark it up something ridiculous.

Can I use romex / NM inside the fixture instead?

That's it.

Each fixture does have to be grounded, but those grounds can be chained together also.

I use 12-2 MC for everything. This way I don't have to worry about adding more lights in the future and then overloading the beginning of the branch wiring. . .

If the fixtures are connected together, they are bonded together, & the grounding conductor does not need to connected at every one, as the fixture channel is the grounding conductor.
