What 3 things are required to induce a voltage in a conductor?
three things required for electromagnet are hands eyes ears have fun! lol
What are 3 things required to induce voltage?
A magnetic field, a conductor and movement.
What size grounding conductor is needed for a 80 amp service?
For service sizes of 100 amps and less a #8 bare copper conductor is required.
How do you do for phase sequence protection at three phase motor operation?
motor is designed to operate in forward and reverse direction for the purpose of elevator. Phase sequence protection is not required.
What is the minimum cable size required for 400Amps incoming supply?
A 600 MCM copper conductor with a insulation factor of 75 or 90 degrees C is rated for 420 and 455 amps respectively. To reduce the wire size from a single conductor, a parallel feed of 3/0 can be used.
Is a ground fault protection for equipment required even if the neutral will not be used?
Yes, ground fault protection for equipment is requiredeven if the neutral will not be used.However, the question implies that it might not be required if there is a neutral. That is not true. With two exceptions, ground fault protection is always required in the US, and it is probably required in other countries as well.The exceptions are the use of an electric cooking range, and an electric clothes dryer. In those cases, the US NEC allows the neutral conductor to also be the ground fault conductor, except for the case where the range or dryer is in a mobile home. In the case of the mobile home, the ground fault conductor and the neutral conductor must be maintained separate and distinct all the way back to the distribution panel.In every other case, including where local code overrides the US NEC's exceptions, it must be understood that ground fault protection (protective earth ground) is not the same as neutral, even though the neutral conductor is grounded.
Does one tip a conductor on a train?
A person is not required to tip a conductor on a train. Amtrak doesn't discourage tips, but advises customers that tips are not required for either the attendants or the conductor of the train.

What is the required color identification for the core of a protective conductor?
In Europe, the standard color for the protective (earth) conductor is a green/yellow stripe, although in most residential two-core (line and neutral; the protective conductor isn't counted) wiring, the protective conductor is bare.
