Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized

how to connect cables to switches 240 box
A 240 volt street light circuit is wired in parallel connections. In the base of the street fixture an inline fuse is connected into the circuit that goes up to the fixture to protect the lamp head.
See Discussion Page
For the 120 volt outlets on the wall use a 20 amp breaker wired with AWG #12 wire. The circuit must be GFCI protected. Any 240 volt outlets must be wired according to what they will be powering.
A 240 volt breaker can be removed and replaced with 2 - 120 volt breakers. The existing 240 volt breaker should not be used to supply 2 separate circuits.
What you are probably looking at is a 240 volt three phase system with the secondaries wired in an open delta configuration.
A #4 copper conductor will limit the voltage drop to 3% or less when supplying 30 amps for 400 feet on a 240 volt system.
what kind of circuit? if it's a subfeed from one panel to another same size as hot wires. if it's a straight 240 volt circuit #8. depends on what kind of circuit.
Yes, you can always have heavier wire than code requires.
It depends on the use it is being put to. It is sufficient for a 24 volt circuit. Too much for a 12 volt circuit and too little for a 240 volt circuit.
Yes, GFCIs can be installed on 240 volt circuit. GFCIs protect against electric shocks from ground faults. They trip the circuit if the current is more than a certain level.
No. This is due to the configuration of the distribution panel. Every breaker to neutral bar is 120 volts. To obtain 240 volts the breaker has to span two of these adjacent breaker spaces. To accomplish what you want will take three spaces. One for the 30 amp 120 volt and two spaces for the 30 amp 240 volt circuit.
A 20 amp 240 volt circuit can provide 4800 watts.4800 watts / 6 watt per foot = 800 feet.
Both legs of a 240 branch circuit need to be fused with a fuse rated at 240 volts or better. The voltage potential across the load is what governs the fuse voltage ratings.
red orange and yellow
in the direct way no , you must use a converter
Can you supply three 220 -240 volt 16.6 amp infrared heaters with one circuit?
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
Yes, in the form of GFCI circuit breakers, not as a receptacle.
Yes a 10 amp fuse can be used to protect a 240 volt circuit. The amperage rating of a fuse is based on the given amperage load of the circuit. The voltage rating on a fuse must match or be higher than the voltage that is applied to the fuse. In other words you can not use a 240 volt fuse on a 277, 347, 480 or 600 volt circuit but it can be used on a 120 volt, Manufactures of switching equipment today make it impossible to interchange different voltage fuses to be installed in higher voltage switches.
If it is a four wire (ie grounded) circuit, and the phase to neutral voltage is indeed 240 volts, then you can.
A two pole, (220-240 volt) circuit breaker can go anywhere in a panel where it will physically fit, connecting to two poles on the buss bar. However, if you don't know this already, you probably shouldn't be fooling around in a live electrical panel. You can get seriously hurt or burned.
Nothing happens. That is the way that combined loads are connected from a service distribution panel. If there is only one load on the circuit from the distribution panel it can also be classed as a series connected load. More than one load on the circuit then the classification is changed to parallel.
