Do I need a separate ground wire to the garage?

Answer by  theturtlepond (44)

Yes the garage needs a separate ground wire if it is a disconnected garage. Every building needs a ground wire but if the garage is connected to the main building then it can be connected to the main building's wires. Without a proper ground this can lead to electrical problems and even fires.

Yes. Especially if the garage in question is detached from the rest of the home. If not it is debatable. Treat it as though it is a completely new and seperate panel when laying the rod.

If the garage is connected to the house, it is part of the same structure, and the grounding would be the same as any other "room" in the structure. If the garage is detached, either a ground wire should be run along with the conductors to the garage, or a "separately derived" ground (ground rod or UFER) should be installed.

This depends on your garage structure and your home. If the garage is attached then the grounding would be the same as every room in the house. If the garage is separate then the wire would be a separate ground. You can also have a separate ground if you want.

Yes, a separate ground from the main circuit breaker panel is required. While a locally available ground is convenient, it may be at a different actual voltage level compared to the main panel. The electric utility's ground is connected to the main panel ground and must be consistant.
