Yes, most definitely. A few years ago NEC (the electrical code) was revised to allow this type of retrofit grounding. There is no need for the ground wire to follow the same route as the conductors.

Do I need to ground a 3 prong dryer?

Have you wondered why this is or have you had trouble connecting your dryer to your home electrical dryer outlet because they don’t match? The old style of 3-prong dryer cords did not include a ground wire. Changes in the National Electrical Code now require dryers to be wired with a ground wire.

Where does the ground wire go on a 3 prong dryer?





The screw on the top of the first picture was connected to a green wire on the cord. When touching the exterior of the dryer, this is used to ground the case and prevent shocks. There is no ground wire on the cord with the 3-pronged plug.

Is a 3 prong dryer outlet up to code?

Homes built before the mid 90’s only required 3 prong receptacles, but in 1996 the National Electrical Code (NEC) mandated all new home wiring use a neutral for Dryer and Range electrical circuits.

Can you put ground and neutral together on a dryer?

DO NOT connect the ground wire to the grounded (neutral) conductor, as this could lead to current flowing through the body of the dryer (and potentially through you).

How do you ground an electric dryer?

To ground the dryer, loosen and remove the center screw on the power block. Insert the screw through the hole on one end of the grounding strap and into the hole in the center of the power block. Tighten the screw down. Tighten the other end of the grounding strap under the green screw on the dryer’s frame.

How do I know if my dryer outlet is grounded?





Once you know a 3-slot outlet has power, take the probe out of the large (neutral) slot and touch it to the center screw on the cover plate. The tester should light if the ground connection is good and the receptacle is connected properly.

Can neutral and ground be connected together 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.

What happens if neutral touches ground?

Connecting the neutral to the ground makes the ground a live wire. The neutral carries the current back to the panel. But the ground doesn’t carry a charge, not unless something has gone wrong (such as a short circuit) and it has to direct wayward electricity away from the metal case of an appliance.

Should neutral to ground have voltage?

Some neutral-to-ground voltage should be present under load conditions, typically 2V or less. If the voltage is zero with a load on the circuit, then check for a neutral-to-ground connection in the receptacle, whether accidental or intentional.

Why is there 120 volts on the neutral?



In a normal situation with the neutral path intact, you would have 120 volts measured from across the light bulb or the receptacle. In this case, both sides of the light (hot and neutral) are the same, thus no potential difference (voltage), and the bulb does not light up.

What happens if ground and neutral are reversed?

This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair.

Should there be 120v between hot and ground?

You have to measure neutral-ground or hot-ground. If neutral-ground voltage is about 120 V and hot-ground is a few volts or less, then hot and neutral have been reversed. Under load conditions, there should be some neutral-ground voltage – 2 V or a little bit less is pretty typical.

Why do I have voltage between neutral and ground?



Neutral-to-earth voltage can be caused by a number of factors, both in and around the farm. The amounts of minerals and moisture in the soil, subsoil and rock strata, and the varying water table level can affect any grounding system and change N-E voltages.

Should ground wire have voltage?

Does this mean that the grounding wire has voltage? The neutral-ground voltage should be 2 volts or less under load situations.

How can you tell a neutral from a ground?

Neutral wires should be white. However, if you see a white wire with electrical tape on it, that may indicate that it’s being used as a hot wire. And ground wires are often plain copper, but the ground wire color can be green. It’s also possible to have some other colors may come into play depending on the system.
