If the person working on a circuit is unqualified, any voltage is dangerous! If you have not been properly trained, stay away!

Why and how does insulation depend on voltage?

Where you find wire insulation with ratings of 300 volts, 600 volts and 1000 volts, these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, insulation on a wire is tested to destruction. The label that is given to wire's insulation, as a result of the tests, is the highest safest voltages that can be applied to that particular wire. So when you see a wire that has a label stating that it is rated for 300 volts it means that any voltage under and up to 300 volts is safe to apply.


What is 9 volts across a 300 ohm resistor?

9v


Why 30 to 40 volts of DC Is dangerous to us?

Volts alone is not dangerous, but volts does causes amps. Amps can be dangerous to you if it flows through your body. That's because your brain, your nerves, and your muscles ... including your heart ... all operate on tiny natural volts and amps. They can all go haywire when big ones get in from outside your body.


If a light bulb is connected between 2 wires and both wires have 300 volts of electrical energy is the light bulb lit?

A light bulb connected between to wires, each having 300 volts to ground that are in phase, will not light, because there is no differential voltage available to do any work. If each wire has 300 volts to ground and are out of phase (600 volts between them) the light bulb will be lit, if it is rated at least for 600 volts, otherwise it will burn out.


Is there a voltage carrying limit of wire?

Yes it depends on many variables such as what the wire is made of the size of the wire whether the wire is a multi strand wire. What governs the amount of voltage a wire can carry is the insulation that is wrapped around the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, insulation is tested to destruction. The label that is given to the wire insulation as a result of the tests is the highest safest voltages that can be applied to that particular type.

Can you run a 60 watt light bulb on a 300 volt wire?

If your light bulb voltage rating is under 300 volts then yes it can use 300 volt wire. The voltage rating of the wire is the maximum voltage that the wire can safely carry. The three common insulation groups is 300 volts, 600 volts and 1000 volts.

What is 300 VAC?

300 VAC stands for 300 volts AC, which is the measure of electrical potential difference in an alternating current (AC) circuit. It signifies the peak voltage that the circuit can reach.

HoW many amp is 300 watts?

As asked, the question cannot be answered. At 1 volt, 300 Watts = 300 Amps. At 10 volts, 300 Watts = 30 Amps. At 100 volts, 300 Watts = 3 Amps. At 120 volts, 300 Watts = 2.5 Amps. At 240 volts, 300 Watts = 1.25 Amps. To calculate the relationship between Amps, Volts and Watts, use the formula: Watts = Amps * volts

Can a 125 volt cable power a 120 volt piece of equipment?

The first thing we have to do is clarify the question. A cable rating of 125 volts is an insulation rating of the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, equipment is tested to destruction. The label that is given to wire as a result of the tests is the highest safest voltages that can be applied to that particular wire. So when you see a wire that has a label stating that it is rated for 300 volts it means that any voltage under and up to 300 volts is safe to apply. So to answer the question yes, the 125 volt insulation rating on the cable can be used to supply a source of 120 volts to a 120 volt rated piece of equipment.
