In large control cabinets the test leads of the testing equipment sometimes are not long enough to stretch from the control transformer X2 terminal to the circuit that needs to be tested for voltage. If you have a control transformer for the control voltage, ground the X2 terminal of the transformer to the control panel enclosure. Tracing circuits now becomes easy as one lead of the tester can be used to test for voltages while the other test lead can be taken off of any metallic structure of the enclosure that the control circuitry is enclosed in.

What is an electric shared neutral?
An electric shared neutral is the white or negative wire that is shared between two electrical circuits on a basic single phase system. Most electrical devices use 120 volts and require a "hot" wire and a neutral wire to operate. Some larger devices use 240 volts and require two "hot" wires to operate. Two circuit breakers in an electrical panel can share one neutral wire as long as the breakers are not on the same "leg" of power. When looking at an electrical panel there are usually two "legs" of power feeding all the breakers, each leg has 120 Volts to ground, if the "legs" are combined you will have 240 Volts. A neutral wire can be shared by two circuits as long as the breakers are on separate "legs". If someone needed to add two circuits in their home, the could run what is called a 3-wire romex, It has a black wire, a red wire, a white wire and a ground wire. The white wire is the neutral for both the black and red 120 volt circuits, and the breakers for the new circuits would need to be on separate "legs" in the panel.
Does sugar create electrical resistance?
Sugar is not used in electrical circuits.
What is the need for neutral wires in circuits for electrical services?
The neutral provides a path back to the source for the electricity. In a three-phase circuit, it is mainly used to carry the unbalanced load back to the source. In theory, a perfectly-balanced three-phase circuit would not need a neutral, but this is almost impossible to achieve in actual practice.
Why neutral solution is not a good electrical conductor?
neutral solution does not contain free ions.
Why is accumulation of moisture in electrical appliances dangerous?
The water can cause circuits to short or ground out, with hazards of electrical shocks or fires.
What type of electrical trouble occurs when a hot conductor comes in contact with a neutral conductor and bypasses the load device?
shorted circuits
How are electrical circuits different from magnetic circuits?
What are the differences between electrical and magnetic circuit.
What are the basic features of an electric circiut?
First, circuits have devices that are run by electrical energy. Second, a circuits has a source of electrical energy. Third, electrical circuits are connected by conducting.
Do all circuits contain electricity?
All electrical circuits do.
In automotive electrical circuits current is considered to flow from?
In automotive, electrical circuits current is considered to flow from the battery. Most cars will have a 12-volt battery which will provide the electrical circuits current.

What is the code ruling in the US on 3 phase branch circuits and the neutral?
A three phase system will have 3 phase branch circuits and no neutral.
What is the significance of resonance in electrical and electronics circuits?
circuits go round
How many neutrals for three-phase multi circiuts?
For a three phase distribution system there is one neutral. In North America the electrical code allows three individual branch circuits to connect with one neutral as long as the three circuits each use an individual phase leg. This differs from 120/240 volt single phase wiring where only two legs can be used with one neutral.
Does sugar create electrical resistance?
Sugar is not used in electrical circuits.
What a short hand way of drawing electrical circuits?

What are the 2 main electrical circuits?
The two basic types of circuits are series and parallel circuits.
