It means that the 240 volts is connected directly to the device rather than being connected through an outlet. In some cases an electric box may be wired between the power supply and device and could contain fuses, breakers or a disconnect of some type. For example if you have an outside air conditioner there should be a disconnect box on a wall near the unit. The unit would still be considered to be hard-wired.
In residential wiring, if it is used as a switch leg or in 3 wire 240 volt circuits.

In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
No, a 240 volt device runs on 240, and a 120 volt device runs on 120. Attempting to run a device on incompatible voltage results in damage.
The 240 volt receptacle has to have an amperage rating. It is this rating that governs the wire size and breaker size to feed the circuit. The new two pole breaker will be inserted in the 100 amp distribution if space is available and connected to the new wiring that terminates at the new receptacle.
No, you cannot simply change the wall plug to make a 110 volt outlet support a 240 volt appliance. The voltage requirements of the appliance and the outlet must match for safe operation. You would need to install a dedicated 240 volt outlet and ensure that the wiring and circuitry can handle the higher voltage. It is recommended to consult a licensed electrician for this type of electrical work.

If you mean 110/240, yes, but there may be a hidden switch to switch it to 240 volt mode. Check the manual.
Yes, you can typically find wiring diagrams for 240-volt electric heaters in the manufacturer's installation manual or on their website. It's important to follow the diagram carefully to ensure safe installation and operation of the heater. If you are not comfortable working with electrical wiring, it is recommended to hire a professional electrician.

If you mean a dual voltage motor 120/240 then yes these will operate on a 240 volt home distribution system.
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
Yes
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.
