What size wire do I need for a 60 amp sub panel?

That would be 4-gauge wire. In practice, however, it’s common to wire 60-amp breakers with 6-gauge, 3-conductor wire because an appliance that needs a 60-amp breaker seldom draws the full 60 amps. If you’re installing a 60-amp subpanel, however, it’s best to connect it to the main panel with 4-gauge wire….

Why is neutral wire thinner?

Because the neutral wire takes almost no current. So result is that the net current in the neutral is usually smaller than the currents in the live wires. If the current is smaller then the resistance can be increased by using thinner wires without too much of a loss of energy.

Can neutral be used as 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. However, if there is something wrong and the neutral is disconnected, it will make the appliance dangerous.

What is the difference between phase wire and neutral wire?

Neutral is the return path for an AC circuit that carries current in normal condition. This current could be primarily because of the phase current imbalance. The magnitude of this current is a fraction of phase current or in a few cases even double of the phase currents.

Why does the neutral wire carry current?

It is the role of the neutral wire to carry any current as a result of the imbalance in impedance of each of the phases loads. The voltage between the phase wire to earth would be 220V, so the phase wire would alternate current direction between maximum positive and maximum negative peaks of the AC cycle.

Why do I have power on my neutral wire?

3 Answers. Any plugged in and turned on device, for example a light bulb, makes a connection between the hot and the neutral. This enables current to flow through the light bulb and power it. If the neutral is then no longer hot, this confirms that a neutral is disconnected in the circuit….
