We are installing some ETH-SP and they need to be grounded.
We have a Hannah enclosure on the exterior of an apartment building. Electrical is connected to panel, where the ground and neutral are shared. No dedicated ground busbar.
The Hannah enclosure has a metal mounting plate, with provisions for it to be grounded. Our thought is to connect this backing plate to the electrical ground, then connect the ETH to the plate.
Will this work?
For surge protection, is it OK to use a ground that is a shared neutral/ground? Or do we need to install a grounding rod?
