Look for the small print that says, "common". That's the "unswitched" feed. The other two connections are connected to "common" depending on the position of the switch.
AnswerAccording to my husband, all sockets are double pole, single and double pole refer to switches. Hope that helps. Double pole isolates both neutral and live, single pole only isolates live, double is better, but single is cheaper. DP-switched sockets have only become commonplace in relatively recent times anyway, marketed on yet another "increased safety" angle when there was never any safety problem with SP to begin with.
DPST is short for double pole, single throw. Double pole means that the unit contains two identical switches, side by side, and operated by one single toggle or lever. This means that two separate input wires can be controlled by a flick of one toggle. Single throw means that each switch can make or break a circuit; it can connect the input wire to the output, or not. It can't connect to one or other of two output wires, switching between them. A DPDT switch is also used for a disconnecting a 240 volt supply from a 240 volt load. Some other types of switches are Single Pole Single Throw (ordinary light switch), Single Pole Double Throw, Double Pole Double Throw, Triple Pole Single Throw and Triple Pole Double Throw
This looks like a question that has come out of the middle of a conversation. Us poor guys trying to answer the question don't have any context. We don't know what the intermediate switch is; or anything else about the system. You can always use just one side of a two pole switch to replace a single pole switch.
You switch the hot side instead of neutral, because there is a shock hazard otherwise. If a fault caused hot to connect to a metal part on the device, you would get shocked touching the metal part. Sometimes a double pole switch will switch both hot and neutral in special applications. It is never a good idea just to switch neutral.
If the neutral and hot wires touch on the same pole of a light switch, it can cause a short circuit. This can result in overheating, potential damage to the electrical system, and a risk of fire. It is important to address this issue promptly by disconnecting the power and fixing the wiring.
The switch will have two termination points at the top or one side called the line side of the switch. The corresponding bottom or other side of the switch will be called the load side of the switch. Terminate the two wires from the distribution breaker to the line side of the two pole switch. Terminate the motor to the two terminals on the load side of the switch. On a motor switch there should be a place where an overload protection can be screwed in. Order the overload heater element to the sizing of the amperage on the motor's nameplate rating.
Yes - but for only one side of the circuit. The other side must be joined ad it will then bypass it's side of the original switch. So what ever that is will not be switched. You got good insurance?

Use a volt meter to measure the voltage to neutral on each side of the switch. By turning the switch on and off and monitoring the voltage on one side and then the other, you can determine the supply and load side of the switch.
If the neutral and hot wires touch on the same pole of a light switch, it can cause a short circuit. This can result in overheating, potential damage to the electrical system, and a risk of fire. It is important to address this issue promptly by disconnecting the power and fixing the wiring.
The recommended wiring diagram for a 60 amp disconnect switch typically includes connecting the power source to the line side of the switch and the load to the load side of the switch. It is important to follow the manufacturer's instructions and local electrical codes when wiring the disconnect switch.
Get on the pole. Now get ready for this-as soon as you see the brown coconut (like some of the bottom half of it) quickly switch to the other side. Now do not get confused if you are (let's say) on the left side and a coconut is on the RIGHT side DO NOT SWITCH. You could easily lose the game if you do that.
put a 3 prong -power - load - ground, switch on the (+) side of the coil .....
Yes . Although a double pole switch is not needed.In section 26 it states that circuit breakers shall open all ungrounded cicuit conductors simutaniously. All you rally need is a single pole switch but you have a double pole switch .
