Warehouse lighting retrofits are booming here in the hoosier state. I am curious if it is common where you are from to order T-5 high bay lights with fixture cords installed? If so, are they just hard wired into the j-box previously used to feed the MH or HPS it is replacing? I must admit this is the norm around here and I am as guilty as the next guy. It is my understanding that any luminarie with a cord connection must be terminated in a "grounding type attachment plug cap or bussway plug" per 2008 NEC 410.62.C.2.c. What say you?

Are these SO cord whips with twist locks or just flex whips with no plug?

We've never ordered high bays with fixture cords in them. We always use BX and wire them up on the ground then load them up on the lift and hang it. Then all you have to do up on the lift is wire it into the j-box

I have ordered both ways...if they are currently hardwired, I follow suit and wire with soow... If there is a receptacle, I order with pigtails already installed. As long as the new fixtures have the ballast disco.

Although I can't find where they are required to be twist lock recepts

We use them. I prefer them like that. A lot quicker to install.

These are SJTOOW tails with no cord cap. There is a local contractor who orders up to 20' tails for areas where the new lights will relocate so they can still tie into the existing box. All connections are hard wired with no cord caps. You can imagine the labor savings. It is impossible to compete with.

Im not sure there are straight blade options for 480v receptacles.

Did the code section for this change in '11? I can't understand why you couldn't hardwire those high bays.

They can be hard wired with mc or flex and wire. These lights were ordered from the factory with rubber cords pre installed.

400.7(a)[2] allows you to wire any luminare with a cord.

and 400.7(b) doesnt required a cord cap for (a)[2] installations

I read through the luminaire section of the '11 code while in class the other day and I couldn't find anything that would prohibit hardwiring soow . Is it somewhere else in the code?
