The key is the protection of the wires. If you are using single wires you will need a conduit of some sort. Don't just run the single wires in the wall. Multi wire Romex or metallic shielded cable are used to provided added protection to the encased conductors.
No A intermediate switch can not be used to change three phase to single phase.
A TPST switch is an acronym for triple pole, single throw it allows three different sources of current to be switched off with the single throw of a switch.
The amperage rating of any wire or conductor is determined by its size or gauge. It has nothing to do with whether it is a two, three or four conductor wire. For example, in basic residential wiring, a 14 gauge wire is rated at 15 amps, a 12 gauge wire is rated at 20 amps, a # 10 is rated for 30A and so forth.
That is called a three way switch. It's used in conjunction with another 3 way switch in another area and they both control a light or set of lights. The black is power and the other two are called travelers that wire to the the other 2 gold screws on the other switch. A three way switch can be used as a single pole switch by using the black screw and one of the brass screws. You will have to test the circuit to orient the switch so up is on and down is off, if that is what you desire, because it is not obvious on a three way switch. The green screw is simply your equipment ground. You place your green or bare conductor there.
A two way switch is UK terminology for a North American three way switch. Though the switch has two names it is still a Single Pole Double Throw switch that has three terminals. North American terminology. The circuit is the same as the three way switch system. To control from four locations just add another intermediate switch. For the system to work properly the new intermediate switch has to be adjacent to the existing intermediate switch. The connections must run - three way, intermediate, intermediate, three way.
There is no such thing as a 'phase conductor'; the correct term is 'line conductor'. In a single-phase system, the line conductor is the energised conductor; in a three-phase system, there are three (energised) line conductors.
A three way switch can be used as a single switch. Replacing this switch will not allow you to switch a fixture from two locations unless there is a three wire cable going to the second box.
No A intermediate switch can not be used to change three phase to single phase.
A TPST switch is an acronym for triple pole, single throw it allows three different sources of current to be switched off with the single throw of a switch.
A single-phase cable will have a line and a neutral conductor and, possibly, but not necessarily, an earth (ground) conductor. A high-voltage three-phase cable will have three line conductors. A low-voltage three-phase cable is likely to have three line conductors and a neutral conductor.
Yes, If you only hook up two wire it will work as a single pole
A three way switch is a switch that is used in a lighting circuit that allows the light fixture to be turned on from three separate locations within the building. In electrical terminology this switch is also referred to as a SPST, Single Pole Single Throw switch. The switch has three individual terminals of which two are always connected. These switches are usually located at the far extremes of the circuit with an intermediate switch between them. This intermediate switch is referred to an a four way switch.
A three way switch is a switch that is used in a lighting circuit that allows the light fixture to be turned on from three separate locations within the building. In electrical terminology this switch is also referred to as a SPST, Single Pole Single Throw switch. The switch has three individual terminals of which two are always connected. These switches are usually located at the far extremes of the circuit with an intermediate switch between them. This intermediate switch is referred to an a four way switch.
A single pole switch controls a light or outlet at one location. A 3 way switch controls a light or outlet from 2 locations.
The amperage rating of any wire or conductor is determined by its size or gauge. It has nothing to do with whether it is a two, three or four conductor wire. For example, in basic residential wiring, a 14 gauge wire is rated at 15 amps, a 12 gauge wire is rated at 20 amps, a # 10 is rated for 30A and so forth.
The utility company can provide a 480 volt, single phase service from a single phase transformer, usually with a three wire service. 480 volts is measured between the two line conductors, and 240 volts is measured between either line conductor and the common neutral conductor. The voltage of the line conductors are at 180 degrees with respect to the neutral conductor.
To obtain a single-phase supply from a three-phase supply, the single-phase load must be connected either (a) between any pair of line conductors, or (b) between any line conductor and the neutral conductor. Of course, the voltage obtained from either of these connections must match the voltage rating of the load.
