Electrical Troubleshooting

A shunt trip breaker is installed like any other molded case breaker. The only difference is that it has an internal tripping coil that is usually connected to a C.T. The breaker is usually mounted in a MCC cabinet The top of the breaker is bolted to the MCC bus bars and the bottom of the breaker is connected to the load. The load conductors pass through the C.T.'s.

36 is to 12 as 18 is to 24.

By "pulsating" current, I presume you mean alternating current. If so then the answer is YES. Current, (electron flow) is measured with a device called an "amprobe". It measures current flow in amperes. (the device or circuit you're measuring must be in use and drawing power to get a measurement. An amprobe is that electrical meter with a large "clamp" at the top of it. The clamp must be placed around the hot conductor and only one conductor. For example if you put the clamp around a cord running say a toaster, it'll read 0 because the neutral cancels out the signal of the hot conductor. If you're measuring a 3 phase device, you again must measure each of the three "hot" wires individually. The three "legs" should all be close in their amp values. You can average them, but note the highest value is the critical value. Also note that if you look this up on say Google, be aware that "Amprobe" is a brand name of the first company who made these devices. (I still have an original from the 70's) Now virtually all electrical meter manufacturers make "amprobes."

It keeps the electron flow in check. Wthout resistance, current flow, (or amperage), would be too excessive and hard to control.

Think what would happen if you placed a metal wire from one post of a car battery to the other post (a direct short with no resistance). The wire would melt and overheat and also possibly damage the battery from excessive amperage flow.

The service is not balanced, one leg is drawing more current that the others.

Have you done a Google search? You should be able to locate it.

Any electrical meter which measures volts or a standard plug tester. (the ones which plug into the receptacle and light up indicator lights) As long as the receptacle measures 110-120V between the hot and neutral, and measures 110-120V between the hot and ground, then it is wired correctly and supplying correct voltage with ground reference. To determine if the GFCI is "tripping" or opening the circuit when it should, simply press the test button. If it doesn't trip, (or reset correctly with the reset button) replace the device.

Because that completes a circuit. The live wire is one terminal of a high voltage transformer at the substation. The other terminal is grounded to earth ground, and earth is conductive.

Sorry, there is no such wire size as "30 gauge" in the AWG (American Wire Gauge) system. For the ampacity rating of all standard conductor sizes, go to Table 310-16 of the National Electric Code. If you mean what wire size will carry 30 amps then a #10 copper wire insulation rating of 90 degree C is rated at 30 amps.

When electrical outlets get old they tend to chip and crack. Also in older outlets the socket gets loose and the plug will not stay in the outlet.

CASS EO (electro-optic)

Yes, a transformer has eddy currents.

Yes, you will need to install a second 12V battery in series with your existing 12V battery to supply 24V to the winch. However, to keep them charged, they have to be charged in parallel. You'll need a schematic to do this correctly and not damage the winch or batteries. I recommend you contact the winch manufacturer for a schematic. It might be best to purchase two new 12V batteries to operate the winch and not tie into your Land Rovers battery. I would purchase "deep cycle" marine batteries such as are used in boats and RVs. These will give you the best performance They are available anywhere batteries are sold.

You have to employ the microphone jack on the amplifier providing the signal to the speakers. If you don't have a mic jack on your amp, your out of luck.

Briefly, a megger test is testing an electric circuit at load. The circuit might prove good at normal resistance measuring but fails when applying high voltage. Read the megger result correctly, every electric circuit will fail if stressed high enough. Disconnect any servo drive or frequency controller before testing.

In the wall beside the sink and always in accordance with your local Wiring Codes or Wiring Regulations.

In a location next to a kitchen sink a Ground Fault Circuit Interrupter (GFCI) is likely to be essential to meet the latest wiring and personal safety requirements.

Well work out your CSA size from what you got. If you've got the wiring regulations you can look it up there. Takes some time but you'd find most of it in there on what you need.

The very first thing you do is shut the power off to that circuit if you are going to work on it. A regular duplex receptacle has 5 screws on it. With the receptacle facing you and the U ground pin facing down, the left side (neutral blade, silver screws) connects to the white (neutral) incoming wire. The right side (hot blade, gold screws) connects to the black (hot) incoming wire. The ground wire connects to the green screw on the receptacle Strip and wrap the wires around the appropriate screws. This leaves you two more screws on either side, tighten them snug as no wires go under them. Reinstall the receptacle back into the wall and turn the power back on.

Sounds as though you only ran a 110 volt power supply to your new shop subpanel. You need to supply 220V with a neutral and ground from your main panel to your subpanel. The 220 supply needs to come from a two pole 220V circuit breaker in your main panel. (example 50 or 100 Amp) Then, most importantly, you must use the correct size wire to carry the current. That is the wire must be sized correctly to the 220V breaker. The neutral must also be the same size as the conductors.

Once you determine how much power you need in your shop, size the supply 220v circuit breaker and wire accordingly. Check with your local building department if you are unsure or what size wire to use with what size breaker or refer to Table 310-16 in the National Electric Code.

In Australia domestic power is 240v So you have run single phase power to a three phase switchboard. To get power to those breakers you must hook the active to the busbar connected to those circuit breakers.

Most likely 110-120 volts AC

Because to much electricity is getting through to the light bulb.

It depends on the voltage of your electrical system. The basic formula is watts = volts X amps. So, if your voltage is 120V then the absolute maximum watts available would be 3600 (30 * 120 = 3600). Note that this is the point at which the breaker would trip, so you could not count on 3600 watts for more than a few minutes. A good rule of thumb is to limit your normal load to 80% of the maximum available. In this case, 80% of 3600W is 2880W. If you put a frozen dinner in the microwave for 5 or 6 minutes and happened to push the watts up to, say, 3500, you would probably get away with it. But try the same trick with the air conditioning that runs for an hour or two and you will trip the breaker. Keep the watts below 80% and you can run forever.
