YES. CHECK CONTROL Transformers INSIDE MOTOR STARTER OR MOTOR CONTROL CENTERS IS A GOOD EXAMPLE EVEN UP TO 6 V PILOT LAMP.
No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.
Yes, but the 600 volts would have to be transformed down to 480 volts. Direct connection to the motor with 600 volts would overheat the motor to destruction.
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.
Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
It is not advisable to run lower voltage motor on a higher voltage.
A 6kw load on a 240volt circuit is 25amps.
There are zero amp into or in 240 volts. These are two different entities. A load needs to be connected to the 240 volt supply and then the amps will flow in relationship to the resistance of the load.
Yes it can be transformed from one voltage to the other.
36-volt bulbs are easily found, try Amazon.
No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.
NO
A 2/0 AWG copper conductor will limit the voltage drop to 3% or less when supplying 65 amps for 150 metres on a 240 volt system.
Yes, but the 600 volts would have to be transformed down to 480 volts. Direct connection to the motor with 600 volts would overheat the motor to destruction.
That depends on the wiring, the light socket, switch(es) and any other equipment in the circuit. You should never use a bulb that is larger than the original circuit was designed for.
Using a 10 volt power supply for a 9 volt keyboard is not a good idea. The higher voltage will cause damage to the keyboard, burning it out and making it useless.
Yes.
It is not. Both tools are equally safe. As long as you see a UL or CSA label on the tool it has been tested to a safety standard and considered safe to use. Think of all the tools in Europe that use 240 volt.
