I got a Shenhui 360 and it comes with the grounding wire (no spike). My shop is fully grounded at the outlet. Do I need to use this wire as well?
I imagine a few people out there aren't drilling holes in their concrete shop floors for a grounding spike. If it's required, I was just going to ground it to the air compressor distribution system... a few hundred feet of iron ending at a 80 gallon compressor.
thoughts?
