Hello friends!

I have a project in the submittal phase that will be installed in a C1 D1 Group D environment. Its basically a traversing overhead crane.

We have a solution specified to provide power and signal to the crane that seems like it may not be accepted by the customer as its not PRECISELY rated for C1 D1, but is ATEX rated (sigh).

My question is - what the heck to other folks use in C1 D1 environment when they need to get power to a hoisted crane? Very hard to find anything commercially available.

The code is pretty silent when it comes to continuously flexible cabling in C1 D1.
