You can't do that if the the reels are made of ferrous materials.
3 PH on reels
I have a customer asking for a 3PH reel system.
He wants 3 reels, one phase per reel. Each reel will have a single 4/0 with a male camlock on the end.
- Is this allowed?
- Won't I need a ground with each conductor? If not, then obviously I need a 4th reel for ground.
- How do I ensure the connection order? This is a rental load bank, so how do we prevent the customer from a potentially dangerous hookup? In the past I have spec'd the Cooper Posi-Lock panels:

These ensure connection order and provide a set of contacts for safety interlock. But I'm not seeing how I can accomplish a level of fool-proofness with this reel arrangement.
Thoughts?
