Question: What if there is no ground wire for a light fixture?

If by chance you are installing an electrical light fixture that has no ground wire into an electrical box with no ground wire as well, then simply connect together the hot wire from the electrical box to the hot (black or red) wire on the light fixture. Make sure to use wire nuts to attach the wires together.

Do I need a ground wire for a light fixture?

Yes, if you have a metal light fixture your fixture needs to be grounded. The ground wire exits your junction box, but it is not attached to your junction box.

What if you dont have a ground wire?

Dont ground to the electrical box. Connecting the ground wire to a metal electrical box will energize the box in the event of a short circuit. The box could overheat and start a fire, or someone could get a shock from touching it. The connection is often unreliable.

What happens if neutral and ground are reversed?

If your outlets polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is. There is always electricity flowing out of an outlet with reversed polarity, even if an appliance is supposed to be off.

What happens if you mix up ground and neutral wires?

If you connect grounds and neutrals at a subpanel, the grounds could take some of the power load and deliver it back to the source (the main panel). The is very bad considering grounds are never supposed to have any power except for when there is a surge of power.

Can I connect to ground instead of neutral?

No, the neutral and ground should never be wired together. This is wrong, and potentially dangerous. When you plug in something in the outlet, the neutral will be live, as it closes the circuit. If the ground is wired to the neutral, the ground of the applicance will also be live.

Does the ground wire go to positive or negative?

The cars electrical system is wired with the positive side of the battery going to accessories first and the ground wire of the battery grounding to the frame and chassis of the vehicle, allowing the frame and chassis to complete the circuit. Negative ground is the norm these days.

Why do I have 2 ground wires?

The two ground wires MUST be connected to preserve the ground on the remainder of the circuit. They should be wirenutted together along with a third short piece of bare or green wire of the same size, this becomes your pigtail.
