Neutral Wire Bus Bar

The bare wire is a ground to.

Neutral wire bus bar.

The main feed is 3 wire with 2 hot legs to the main breaker and an aluminum wire to the neutral. The white wire is neutral not ground. You can see this clearly in the picture below as there are multiple neutral wires feeding into a single screw in more than one instance in this spaghetti mess of wires. However the white and bare wires both have the same ground.

Neutral bars are widely used in residential and commercial electrical service panels to terminate all those white neutral or return wires from the many load circuits in the building. Gfci s work differently and can put out a voltage on the neutral to be reconciled later on the ground bus. Neutral bus bar once the power leaves the electrical service panel through the hot wire s of a circuit and does its work through the electrical devices light bulbs outlets etc the electrical current returns back to the service panel through the neutral usually white circuit wire which is connected to the neutral bus bar. Consider the schematic for a flash light.

There is also a bare ground wire from the neutral bar to the water pipes. Your answer is yes you do put in the bare wire with the white wire. And on spas if ground wire is loose or water filled equipment you can have that voltage in water. A double tapped neutral is when more than one neutral wire is fed into a single screw terminal on the neutral bus bar in the main electric panel.

The problem primarily comes from the inappropriately named neutral wire. Information about what is a neutral bar and how it useful in service panels. There is nothing neutral about a neutral wire. If that voltage is not the same it will trip gfci.

It is a current carrying conductor just like a hot wire and has all the potential for danger and should be treated with the same respect. When there is two neutral wires in one hole on the neutral bar of an electrical panel several things may happen. The black hot wires are protected from overload by circuit breakers in the panel which typically sense the current in the hot wire and trip out if current is exceeded for too long.
