I recently failed my electrical inspection for something simple and want to confirm before I hook this up. I have 200amp service to my home. I had an electrician install a 100amp circuit breaker to that panel. This is then run outside underground to a non-attached pole barn structure. At that structure is a new 100 amp panel. So I have 4 wires going into this panel. 1 is the neutral that goes to the neutral buss. 1 is ground that goes to the ground buss, which then has a copper wire attached to the buss that leads to 2 very long copper poles in the ground. The final 2 wires feed into another 100amp circuit breaker that is attached at the bottom of the panel, but it is not separated from the other circuit breakers like the main panel in my house. This feeds all the electric to the panel. I failed because the neutral bar didn't have a bonding strap to the panel itself. So how does one determine if the panel is a sub panel or a main panel to a main panel (i.e. requires the bonding strap). Finally, where does one get that nice S-shaped bonding strap?

I've got an odd request. I have a WINK hub home lighting system and just received a Tapt smart light switch. It basically installed to your light switch panel to control the light and also connects wirelessly to control your smart lights. I live in an apartment and don't want to change the wall switches (also I don't like the available locations). So what I want to do is turn this into a desk switch by using a 3 prong AC plug. The problem I have is the switch is 4 wire, while the plug is 3. The fourth wire is the Load wire which I don't need since I won't be powering a traditional light, only using the switch for the wireless ability. Can I wire this to a 3-prong and just TIE off the Load? Or can I connect the load wire to Neutral? How do I solve this. Thanks guys.
