Electrical Troubleshooting

Electric woks usually do not get hot enough to fully cook the food, and also it is very common for the food to stick rather badly after the cooking process is finished.

There are many sites on the internet where you can search for manuals for different types of equipment.

It is a circuit fuse in a vehicle. The fuse is used to protect the courtesy/clock circuit.

When installing an isolator switch enclosure, make sure that the terminations are tight and secure.If you are using the isolation switch to disconnect a load that must be worked on the following should be checked. Make sure that the handle of the switch is down and locked in the off position. For isolation switches that have windows in the front of them look and make sure that the switch blades are physically in the open position. Then lock the switch in the off position. Always safety first.

They are used to trace wiring. There may be multiple conductors in a bundle that are unmarked, or perhaps unmarked wires that go to different locations. The tone generator is connected to a pair of conductors (or one conductor and ground), and the probe is used to find the same conductor on the opposite end. The probe is used to look for the conductor that is carrying the tone.

In a bundle of conductors, or several conductors in a raceway, the tone may be induced, or "bleed" into other conductors. In this case, the desired wire has the strongest tone. Connecting the generator to one conductor and ground tends to induce the signal into other conductors. Toning a pair, with neither one grounded, is the most selective, making identification more sure.

To make sure that a feeder cable is secure it must be supported. The support distance is stated in the electrical code book. The code also gives support of cable trays, conduit and all the different ways to support cables.

Look very closely for a serial number stamped on the unit. The suggested course of action is to take the alternator to an auto parts store to see if they can recognize what vehicle the alternator should belong to. Automotive alternators are three phase and should have a full wave diode bridge concealed within the alternator housing. If you open the alternator case, the diode bridge will have diode numbers or a number stamped on the bridge network. Cross referencing this number to other diode bridges will tell you what amperage the alternator should be able to output. If you find a number there let the automotive parts store see if they can find a substitute for it.

The centrifugal switch on a motor's start winding should open at 75 to 80 percent of the motors run speed RPM.

The reset is part of the resettable circuit breaker. It is located just below the "not grounded" light that indicates when a ground is not present

As long as the outlet and the fixture are compatible in voltage, amperage and pin configuration, there should be no problem using them together.

The CEC and NEC both cover this in the electrical code of the particular country.

Depending on the circuit, typically a combination of a coil (commonly called a choke) and a capacitor can be put in circuit at multiple places to significantly reduce noise in a circuit.

A good number on a megger test should be around 2 megohms.

loose screws or corroded cables or over current above breakers rating (faulty breaker not tripping when meant to) internal fault with breaker.

FWIW: Here is one answer I learned working with my father in appliance repair.

In older stoves (and probably newer ones) , baking ovens and such, the heating elements at the time consisted of long coiled pieces of nichrome wire that resembled a stretched door spring. These wires were fed through round ceramic doughnut hole type insulator holders mounted on a metal frame. When these elements burned out the element wire would be removed and you could purchase a new one, stretch it out, feed it through all the insulators and terminate the ends to the electrical connector. This was referred to as "Recoiling an element"

Later on preformed metal rode type elements were designed and are primarily used today.

I've never heard of a meggameter. However, since the question is under the heading of Electrical Troubleshooting, I'm assuming that you are referring to a megohmmeter.

A megohmmeter is a testing device that measures the resistance of insulators and insulation of electrical conductors. Since their resistance is generally very high, this device uses a voltage between 500 and 2000 volts at a fixed current.

This combination can detect minute pinhole leaks in conductors that are not visible to the human eye. These pinhole leaks can cause arcing and eventually an electrical short.

First check what's actually serviced by that fuse, maybe you've added something that wasn't there from the beginning, pushing the draw over the allowable limit.

If that still looks OK, start by disconnecting the stuff hooked up to that fuse one by one, see if that can narrow things down.

If that doesn't show anything, then you have to start inspecting the wiring itself for damages.

Dont mess with transformers if u dont know how to read a wiring diagram It is easy if u know your relation to each of the phases and neutral and ground

Are you referring to a meter?.... if so, set it to the closest higher voltage on the meter (usually 600VAC but sometimes 300VAC depending on the brand and model)

closing coil 24 vdc

There may be an "open neutral" somewhere either in your breaker panel or in the meter base.

Contact a qualified electrician to help solve the problem. An open neutral causes one leg of the electrical service to be "low" voltage, while the other leg goes "high". That can result in premature failure of electrical components, such as light bulbs, electronic devices and electric motors.

Yes, this simple primitive tool is the best diagnostic tool for most wiring problems.
