How to wire a 120 volt outlet off a 240 volt line with 20 ...

When the wire gets into the well house it splits and the 240 line continues onto the well pump. Before I ran the new line there was a 120 volt line split off the 240 volt line the wire ran to a 120 volt outlet followed by a light switch run off The same line.

Wiring a 120-volt circuit off of a 240-volt circuit can be useful where there is primarily 240 volts available. This could be the case at a water well or a workshop. A 240-volt circuit is comprised of two hot wires, a common neutral wire, and a ground wire. It is actually two 120-volt circuits which share the neutral or common wire.

A 3-wire, 240-volt circuit has two hot wires—each supplying 120 volts for a total of 240—and an equipment ground wire. A 120-volt circuit has only one hot wire connected to the breaker plus a neutral wire connected to the neutral bus bar in the service panel.

A 120 volt circuit breaker sized for the type of wire and the wire gauge is installed into the panel where the black wire of the converted circuit is attached. More about 240 Volt Circuit Wiring. 240 Volt Wiring Diagram. Wiring 120volt and 240volt Electrical Circuits

As explained above, in a utility-connected, 120 / 240 VAC Single Split Phase System, the 120 / 240 VAC power consists of two 120 VAC lines viz. Hot L1 (Phase A, Red wire) and Hot L2 (Phase B, Black wire) that are 180 degrees out of phase with respect to the center tapped, grounded Neutral (White wire) – see Fig. 1

The Advantages of a 240 Volt Motor. Wiring a 120/240 volt motor for 240 volts is as follows: A balanced electrical load which may save on electricity compared to an unbalanced electrical load. Faster starting power. 240 volt motors will have a stronger start compared to a 120 volt motor.

Homes in North America are supplied with a 120/240V single-phase electrical service. The incoming 240V power is split into two legs. Each leg can provide 120V hot-to-neutral, and the two legs together will supply 240V, which is used to supply heavy loads such as air conditioning compressors and cookstoves.

We see that the current in L2 is now equal to the current flowing in the 240 V Load 3 and the 120 V Load 1. We also see that the current flow in Line 1 is unchanged. Current Flows in a 120/240 Single Phase Three Wire System. Finally, in this diagram we add another 120 V load, Load 2 connected to L1 and Neutral.

Caution: This circuit is connected directly to the power line (120 / 240 volts AC), so you must take special care to test it.. When two Light-Emitting Diodes are connected, the first LED diode will conduct in the negative semi cycle of the wave and the second one will conduct in the positive semi cycle of the wave.

Collection of 480 volt to 120 volt transformer wiring diagram. A wiring diagram is a streamlined traditional pictorial representation of an electrical circuit. It shows the elements of the circuit as streamlined forms, and also the power as well as signal connections in between the devices.
