Your 2-wire system is actually connected to one "side" of the 3-wire system. In your utility's 3-wire system you have 2 hot wires that are attached to each end of a tranformer winding and the neutral is attached in the middle and grounded. Typically in the US this gives you 240v (or something similar) between hot leads and 120v from each hot lead to neutral or ground.
two hot one ground
There should be 2 or 3 wires. A hot, a neutral and sometimes a ground.
It is because the nec standard.
White wire is usually used as a neutral conductor and a 240v ac unit has no neutral. Each leg of the 240 volts is a "hot" leg However, very often a 12/2 or 14/2 NM cable is used to power small window ac units using 240v. In this case one of the conductors is white, but is not a neutral. It is good practice to mark the white wire with black tape so it is readily identified as a hot wire.
A 240V cooktop does not have a neutral wire because it operates on a 240V split-phase system, where 240V is supplied by two hot wires, with no need for a neutral wire. The two hot wires provide the necessary power for the cooktop to operate efficiently.
In North America it takes two "hot" wires to obtain 240 volts.
No, the black wire is typically associated with line 2 in a 240V line. In a 240V circuit, there are two hot wires - line 1 (black) and line 2 (red), as well as a ground wire and sometimes a neutral wire.
No, joining a red and black wire together will not give you 240V. To obtain 240V, you typically need to connect two hot wires (black and red) and a neutral wire. It is crucial to follow proper electrical codes and guidelines to ensure safety.
No, it does not matter which hot wire (red or black) is connected to L1 or L2 for a jet pump pressure switch in a 240V setup. The important thing is to ensure that each hot wire is connected to one of the two load terminals of the pressure switch. Make sure to also connect the ground wire for safety.
Not a hard job or complicated but could be hazardous. Hire a professional.
Reading 230V between neutral and hot on a dryer receptacle indicates a problem with the wiring setup. In a properly functioning system, you should read 240V between hot wires and 120V between hot and neutral. The issue could be due to a faulty connection, break in the wiring, or incorrect wiring at the receptacle. It's crucial to address this issue promptly to avoid potential safety hazards and damage to the appliance.
4 wire household wiring is black, red, (hot wires) white (neutral) and bare or green (ground wire). You say 3 wires. Is it 120v or 240v. If its 240v which is more common just use the two hots and the ground and cap off the neutral wire.
The wires are probably getting too hot.
Based on the description, it sounds like you should wire the stove outlet as a 3-prong outlet since the cable you have appears to have two hot wires and a ground wire (wire braid). Connect the two black wires to the hot terminals and the wire braid to the ground terminal on the stove outlet. Remember to ensure that the circuit is properly grounded for safety.
A 240V GFCI breaker monitors the difference in current between the hot wires, providing ground-fault protection without needing a neutral wire. It compares the current on both hot wires and trips if an imbalance is detected, indicating a ground fault. This system does not rely on a neutral wire to detect faults and protect against electrical shocks.
