The voltage hot to hot is 240 and the hot to ground is 120v L1 is 180 degrees out of phase with L2. This is why the neutral can handle the 2 hots. The grounding system is there to clear a fault without having become energized.

## Why are neutral and ground tied together in main panel?

Without the grounding wire, that misdirected electricity could shock you. At the main service panel, the neutral and grounding wires connect together and to a grounding electrode, such as a metal ground rod, which is there to handle unusual pulses of energy, such as a lightning strike.

## Should neutral be tied to ground?

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.

## Can a neutral wire be connected to ground in panel?

If the main service panel happens to be the same place that the grounded (neutral) conductor is bonded to the grounding electrode, then there is no problem mixing grounds and neutrals on the same bus bar (as long as there is an appropriate number of conductors terminated under each lug).

## What happens if neutral is connected to ground?

In Short if neutral wire touches a earth wire,

An earth wire carrying load current is a risk of electric shock because a person touching this earth may present an alternative path for the load current and thus the risk of electric shock.

## Can ground and neutral be on the same bar in main panel?

The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.

## Do you bond neutral and ground in subpanel?

Here it is: Your ground and neutral wires definitely need to bond (or connect) together. But this is ONLY allowed in the main panelâ€” never a subpanel, or anywhere else in the home. This is a very common mistake we see in the electrical part of your inspection.

## Why are neutral and ground separate?

With ground and neutral bonded, current can travel on both ground and neutral back to the main panel. If the load becomes unbalanced and ground and neutral are bonded, the current will flow through anything bonded to the sub-panel (enclosure, ground wire, piping, etc.) and back to the main panel. Obvious shock hazard!
