I got a 90A main breaker with #3 wires branch circuit going from the MDP to a 100A disconnect feeding a baler with a FLA of 40, baler has full controller with overload and all bell and whistles. The fuses on the baler are 70A right now. Customer wants me to hook up a trash compactor with a FLA of 24. Compactor also has full controller with overload protection. The main for the 90A circuit is 120-140 feet away, but it's almost impossible to run a new conduit to the location without clearing the whole floor. So if I read the tap rule correctly can I?
1: Tap the 90A circuit ahead of the Baler disconnect with #6 wires going into a 60A disconnect and hook the trash compactor? The 60A run will be about 15feet so it falls under the "under 25'" rule.
2: Can i do said taps inside the existing disconnect (just remove the #3 line side from the disconnect and install polaris taps), or do I need to install a box where the polaris taps will be? (I can cut a bit of the conduit and install a box, so it's no big deal to install a box, but I'd rather not).
Thank you.
3: Does the ground have to be for 90A or for 60A on the new tap? I'd assume it'd be required for 90A (the overload is protected on the load side by the 60A disconnect, but in case of a short between???
