Keeping everything same you can skip connecting the ground wire. Step 6: Connect the ground wire to the jumper and the neutral wire to the 3 rd prong as shown in the figure Alternative Procedure: Step 5: Connect a ground strap or jumper to the neutral terminal in the outlet. Step 4: Connect the red and black hot wires in the hot prongs of the outlet as shown in the figure. Step 3: Take the 4 wires and peel off the insulations from the edge of the wires You will see three terminals as shown in figure 4. Step 2: Open the outlet and loosen the screws of the terminals. Step 1: Power off the main switch of the outlet
WIRING A DRYER PLUG INSTALL
The ground and neutral are joined together using a ground strap and then connected to the neutral terminal of the outlet.įig 4: Wiring a 3 prong outlet to a 4 wire install Procedure: To wire a 3 prong dryer you have to connect the two hot wires to the respective terminals of the outlet.
WIRING A DRYER PLUG HOW TO
How To Wire A 3 Prong Dryer Outlet To A 4 Wire Install? Due to which we need 3 prong dryer outlets. Still many such devices are in existence. But before this, the electric setups were designed for 3 prong. In recent times, all houses’ electric design consists of a ground wire to ensure safety purposes. But for the existence of the old models people often need 3 prong outlets. Later on, 4 prong outlets and devices took over the old model. So, the outlets used in homes and other places were also 3 prong. Then Why Do We Need To Use A 3 Prong Dryer Outlet?Įarlier the dryer machines were designed with a 3 prong cord. It contains a ground wire that is connected to the device body for the leakage currents. Thus the 4 prong dryer system was introduced.
WIRING A DRYER PLUG CODE
To prevent such outcomes, a code was approved in the 1996 that all house electric designs should have a grounding wire. Sometimes when the user touches the device with wet hands and bare foot, he gets conducted to the stored current in the body. If there is any leakage current in the body it would pass through the neutral.īut the nature of the current is to pass through the least resistive path. Additionally, the body of the device used to be connected to the neutral. The neutral is used to complete the circuit. Let me enlighten you with some facts about it. So, the current travels back through the neutral to complete the circuit. Because there are two hot wires and a neutral. It is not fully safe to use a 3 prong dryer. The addition of the fourth wire in the 4 prong dryer install, the current can pass through the ground wire in such cases. It cannot pass the current to the ground, thus the current passes through anyone who touches the device. If, by any chance, there is damage in the neutral line or a loose connection, the device becomes a hazard.
In 3 prong dryer install there is only one neutral. The ground wire plays a significant role in assuring the safety of both the users and the electrical device. The presence of an extra ground wire is the main technical difference between the two types.
