A volt free contact is a set of contacts that uses a voltage source from another location. The contacts are used to tie two individual pieces of electrical equipment together so the action on one will cause the other piece of equipment to operate. It is just a new way of using the older terminology "dry contacts". An example of use is the diesel start contacts on an automatic transfer switch. When the transfer switch is in the utility (hydro) position the diesel start "dry contacts" located in the transfer switch are open. On a power failure the transfer switch disconnects from the utility and connects to the generator position. When the transfer switch moves to the generator connect side the "dry contacts" , or volt free contacts, in the transfer switch close. This allows a voltage from the generator control panel (usually 24 volts DC) to return to the start relay located in the generator control panel. This relay engages the starter and starts the diesel generator. On return of utility power the reverse action takes place and the volt free contacts return to their normal state of normally open.

How do you control 110 volt circulator pump with a 24 volt thermostat?
You will need an interpose relay. This relay will have a 24 volt coil. The circuit power for the relay will come from a 120VAC to 24VAC volt transformer. The 24 VAC circuit will have the thermostat in series with the coil of the relay. Thermostat calls for heat, the coil energizes and the relay's contacts close. Your circulator pump is controlled by the relay. On selecting the relay make sure that the contact ratings can handle the full load amps of the circulator. A contact rating of 120 volts at 15 amps will do very nicely.

How do you hook a 220 volt treadmill to a 110 volt wall socket?
A 220 volt treadmill will not run on 110 volt power. if you would wire it to plug in, the low voltage would causes the treadmill to burn up. You will need to install a 220 volt receptacle for it to plug into and work properly. <<>> In the above answer the treadmill will not burn up but at these amperages it will make a very big flash if it shorted out. Also it must be some treadmill to draw 220 amps and I have never seen a 110 amp wall socket.

Can you replace 240 volt service with two 110 volt service?
Generally, yes. Most US home services are 220 volt (240, 220 are `nominal' names) which are split into two 120 volt legs. You can find wiring information ont he internet, but generally, the 220 volt systems have a 120 volt leg, a common ground and then another 120 volt leg. Added together, they're 220 volt but by splitting them, you'll end up with two 120 volt legs. If you're not sure about how to wire them up, contact a qualified electrician to help you. House wiring can be very dangerous if you don't know what you're doing as well as lethal. When in doubt, don't.
