New Electrical Work

The main electric panel is where neutral is bonded to ground. There is usually a screw or strap that connects the two so the same type panel could be used as a subpanel and have the neutral and ground unbonded in subpanel.

There should be two wires in the box, black and white and possibly a bare one depending on the age of the wiring in the house. The fixture has two screws on the base. One wire goes on each screw. If there are short wires on the fixture, black to black and white to white. If there is a bare ground wire in the house box, it attaches to the body of the fixture. If there is no ground screw on the fixture, do not worry about it.

A 1000 watt ballast operating at 120V would draw approximately 8.33 amps of current. This can be calculated by dividing the power (in watts) by the voltage (in volts).

Using the formula for resistance of a wire (R = ρ * (L/A)), we can find the resistivity ratio (ρ_aluminum / ρ_copper) as 1.7 since the total current in both wires is the same and the lengths are different. Knowing that the resistivity of copper is 1.7 times less than that of aluminum, and given that resistivity is inversely proportional to cross-sectional area, the diameter of the copper wire will be √(1.7) = 1.3 times the diameter of the aluminum wire. Since the diameter of the aluminum wire is 2mm, the diameter of the copper wire will be 2mm * 1.3 = 2.6mm.

Your breaker panel has two separate bus bars and it is certainly best to balance your load between each bus. Typically every other breaker, as you move vertically, is an alternating bus.

While you can add up the ratings on each bus to try and balance, this will not provide the best balance in that many breakers may operate at no where near their rating. The best way is to have an electrician measure the current on each bus with a clamp-on amp meter.

While this balance is ideal, it is usually only necessary if you are having a problem with the unbalanced load, like all the lights in your house dimming when the air conditioner turns on.

On your ganged 30 amp breakers, 30 amps through either will trip that breaker.

Yes, the amp rating is a measurement of the highest amp load it should carry. So a 15 amp appliance will work on a 20 amp socket but you wouldn't want to use a 20 amp appliance on a 15 amp socket.

When ever a safety switch is thrown, be it to the on position or the off position, the operator must stand to one side of the switch. It is during the act of opening or closing a switch that a fault could occur. If a dead short occurs when doing this action the whole switch could explode. If the operator is standing in front of the switch their body would take the full force of the explosion.

A ground wire is used for a direct path back to the distribution panel independent of the neutral. On a split phase secondary the neutral is used by other circuits on the system and indirectly makes its way back to the distribution panel. This indirect path introduces a resistance in the neutral which could interfere with an instantaneous trip of the over current device. Using a ground wire from the grounding pin on the three blade plug allows a direct low resistance path which takes the fault current back to the distribution panel which then causes an instantaneous breaker trip due to the high current in a short circuit.

A 3/0 wire with an insulation factor of 90 degrees C is rated at 210 amps. The electrical code book states that 3 - 3/0 wires can be pulled into 41 mm conduit (1-1/2"). Most mast kits utilize 53 mm (2") schedule 40 conduit.

For a 50-foot run with a 6.3-amp load at 240 volts, you can use 14-gauge wire as it can safely handle up to 15 amps. If you want to take into account voltage drop for longer runs, you may opt for even thicker wire like 12-gauge to minimize power loss. It's always a good idea to consult with a professional electrician for accurate recommendations.

The amp requirement for running a well depends on the size of the well pump. On average, a household well pump may require anywhere from 10 to 20 amps to operate efficiently. It is important to check the specific amp requirements of your well pump to ensure it is properly powered.

14 gauge wire is rated for 15 amps wich is the smallest size breaker that is used in the US. I never heard of or saw a 10 amp breaker and I am a licesened electrical contractor

The 2008NEC (NFPA70) lists 16AWG copper allowed for up to a 10 amp CB, and 18AWG copper for up tpo a 7 amp CB, max current. Continuous loads must be derated to 8 amps and 5.6 amps respectively, see NFPA 70 2008, §240.4 (D) (1), (2)., but these are only going to be found in industrial applications.

Would the asked be so kind as to tell us what kind of equipment the 1 amp breaker is on?

14 AWG is still the minimum for a 15amp CB in general, this change might not be wise without an electrician looking at the entire circuit.

Using different wattage halogen bulbs on a track can cause uneven lighting and potentially overload the track's wiring system. It is best to use bulbs of the same wattage to ensure consistent lighting and prevent any electrical issues.

This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.

A 15 amp breaker will trip at 15 amps at an ambient temperature of 40 degree C. If the ambient temperature is higher the breaker will trip before 15 amps and if the ambient temperature is lower the breaker will trip after 15 amps.

GFCIs can trip due to a ground fault, which occurs when electricity leaks from the circuit. This can happen if water or moisture gets into outlets, there is a wiring issue, or there is a fault in an appliance. Tripping is a safety feature that cuts off electricity to prevent electric shocks and fires.

The recommended amp size for 22 gauge wire is typically around 3 amps. However, it is recommended to consult the specific ampacity chart provided by the National Electrical Code (NEC) or a qualified electrician for accurate information based on the application and conditions.

To make a load calculation, you'd need the voltage (volts) and the current (amps) in the distribution line. That would give you the power consumption (watts), and you could find that by multiplying volts times amps. P = I x E [Power equals current times voltage.]

I = W/E. 1500/240 = 6 amps for each heater. In parallel the total connected load will be 12 amps. A #14 conductor is rated at 15 amps and de rated to 80% can carry 12 amps continuous. The breaker needed for this would be a two pole 15 amp breaker. If this is a new installation I would use a #12 conductor for the two heaters on a two pole 20 amp breaker. The conductors will run much cooler using a larger size.

A: Pacemaker battery is designed to last years. It only does any work when it is necessary. Your doctor is the best way to analyze the validity of the battery and it is safer that way. I read in a medical journal that most pacemakers last longer then the host. Do not worry about but do see your doctor to make sure.

At 120 Volts your heater is drawing about 12.5 Amps. If your house only had 120 V then it would draw 13.6 Amps.

Problems could be

1.) Other devices on same circuit.

2.) Internal short in the heating element that reduced resistance and increased current.

3.) Faulty heater in that it really delivers more than 1500 watts because heating elements are less resistance than rating would require.

4.) Faulty breaker.

These are in order of likelihood. You are close enough to the limit of the breaker that it could be any of these things. Typically you should not exceed 80% of the breaker rating and that is just where you are operating.

It is generally not recommended to mount a 20 amp duplex receptacle above a hung ceiling due to accessibility issues for maintenance and safety concerns. It is important for receptacles to be easily accessible for inspection, maintenance, and in case of electrical issues.

Yes, over time the heating element can break, wires can break, or the thermostat can become defective. They will however last for years if they are quality made. No electric device lasts forever.

If the neutral and hot wires touch on the same pole of a light switch, it can cause a short circuit. This can result in overheating, potential damage to the electrical system, and a risk of fire. It is important to address this issue promptly by disconnecting the power and fixing the wiring.
