Conduct a Hi-Pot test on the full length of cable (ensure safety and qualified operator) for a predetermined time at a predetermined voltage. Verify ground straps are properly earthed before test. Test results for a good stress cone installation will be about 35-50 Micro-amps.

What voltage should 208 3 phase leads read?
From line-to-line (any two of the three leads) voltage or 'line voltage', the voltage is 208 V. The line-to-neutral (one of the three leads and the neutral conductor), or 'phase voltage', is 120 V.
When upsizing wire for voltage drop how much smaller can the neutral wire be the next phase conductor?
The neutral wire should be the same size as your conducters
Why voltage are not produce in netural wire?
First of all, by definition, 'voltage' is another word for 'potential difference', and a potential differenceexists between two different points. So a single conductor cannot experience a 'voltage' or 'potential difference'. Your question, therefore, should ask why a neutral conductor has no 'potential'. By general agreement, potentials are measured with respect to earth (ground), which is arbitrarily assumed to be at 0 volts.The answer is that a neutral conductor is earthed, or grounded, so theoretically its potential must be the same as earth -i.e. 0 volts. But, in practise, due to the resistance of the conductor that connects the neutral conductor to earth, the neutral conductor can often have a potential of several volts with respect to earth.
When testing a power transformer with an ohmmeter which winding should have the largest ohmic value?
The higher-voltage winding has more turns (therefore its conductor will be longer) than the lower-voltage winding and, because it will carry less current, its conductors will have a lower cross-sectional area. Consequently, the higher-voltage winding will have a higher resistance than the lower-voltage winding.
How to reduce voltage drop during long transmission of power?
You reduce voltage drop by increasing conductor size. As a general rule, if you believe you have a voltage drop problem, install the next size larger conductor.Voltage drop can be calculated using the formula E=IR, where I is the anticipated current required by the load, R is the resistance of the conductor, and E is voltage, or in this case is voltage drop. If the answer for E is more than 3% of the circuit voltage or 5% of the service voltage, you need to increase conductor size.AnswerBy increasing the supply voltage of the transmission line. This is why very high voltages are used in electrical transmission systems.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
In an experiment of finding energy gap of a semi conductor by using diode what is the junction voltage?
The junction voltage of the circuit should be nearlyb 1.5 to 2v to be maintained which is fixed voltage...
What voltage should 208 3 phase leads read?
From line-to-line (any two of the three leads) voltage or 'line voltage', the voltage is 208 V. The line-to-neutral (one of the three leads and the neutral conductor), or 'phase voltage', is 120 V.
What should you wrote in notification letter about termination?
In a notification letter about termination you should consider including the following: Reasons for termination; Terms of termination; Whether good recommendations will be given; Sincere apologies.
What is the difference between power limited and power non-limited electrical circuits?
In wiring or cabling, high voltage lines and low voltage lines should be separately installed. High voltage lines which carry AC 120V/208V/277V/480V should be installed in one conduit, and low voltage lines which carry DC 12V/24V/48V and non-current carrying lines should be installed in another separated conduit. It is one of the strict requirement of NEC. When AC 120V wires and DC 12V wires are laid inside of one rack, they should have spaces more than 6 inches between them. - dona

How do you provide some method of voltage division to meet equipment used?
Voltage division is a very complicated way to change the voltage supplied to a piece of equipment. You need to install a transformer, if the difference is significant, and transformers should only be installed by qualified professionals.
Termination Letter?
Get StartedA Termination Letter can be interpreted as a legal document by a court of law should your company be sued over the termination. For this reason, the Termination Letter should not conflict with any employment agreement or contracts you signed with the employee. Brevity is important when creating a Termination Letter. The contents should be limited to contractual responsibilities of the terminated employee, the reason for the termination, and instructions for receiving termination benefits. Each state has separate termination requirements, and it is your responsibility to ensure the Termination Letter complies with your state's laws. Be sure to consult an attorney if you have any questions or concerns about terminating an employee.
What is the minimum size AWG copper conductor permitted for conductors with a 0 to 2000v voltage rating?
When you talk of voltage, you should be thinking of the insulation factor of the wire. By the same token when you talk of wire size, it is based on the amperage the wire is required to handle.

The higher-voltage winding has more turns (therefore its conductor will be longer) than the lower-voltage winding and, because it will carry less current, its conductors will have a lower cross-sectional area. Consequently, the higher-voltage winding will have a higher resistance than the lower-voltage winding.
What does the points X N L1 and L2 mean in the defrost timer?
In electrical terms X usually refers to a transformer's secondary terminal output. Example X1, X2, X3, and X4. If the timer is a clock defrost timer then the X represents a point where the timer release relay connects to.The letter N represents the neutral conductor. On controls it should be a white wire.L1 represents a line conductor which means a "hot" wire. From L1 to N the voltage applied should be 120 volts.L2 is a second line conductor, the voltage applied across L1 to L2 should be 240 volts.
What is a Statiscope made by Minerallac Electric Company in Chicago Illinois?
The statiscope is primarily designed to detect the electric field of a high voltage conductor, whether bare orinsulated. The end of the statiscope just has to come near the conductor, it does not actually have to come in contact with the conductor. In fact, it is probably best that it doesn't unless you know just how high the voltage is. When the presence of a high voltage field is detected, the neon tube will glow. The statiscope should be tested both before and after use by using a known energized high voltage circuit. That is done to be sure that the statiscope has not failed and that it will give, and has given, an accurate display. (One handy use for the statiscope is for checking the presence of proper voltage to auto spark plugs)
