White goes to neutral. White is an incorrect color for ground.
Upon further investigation you might find, however, that the white wire is connected to the casing of the appliance. If this is true and if this is the only function of the white wire then it is truly a ground wire. It should be wired as such to the outlet and it should be marked on both ends with green tape or paint or some other method of marking, or it should be replaced with a green or bare conductor.
If it serves the purpose of ground and neutral you may want to consider replacing the cable with a 4 conductor cable and isolate the neutral from the ground.

How many 75 watt bulbs can be placed on track lighting with 20 amp breaker?
Theoretically a 75 watt bulb at 120 volts draws .625 amps. You would add the individual currents to determine maximum amperage. That would be 32 bulbs. However, you would then be right on the edge and breaker would likely trip often. You should de-rate to 80% of the breaker rating or 16 amps in this case. That would be 25 bulbs. You should also check to see if there is a maximum amperage or wattage rating on the track. Twenty Five bulbs will create quite a heat source.
No, you cannot use an existing 8 3 wire hooked to a 30amp breaker for a heater that requires 10 2 wire. The wire gauge and breaker size need to match the specific requirements of the new heater to ensure safety and proper function. You will need to upgrade the wiring to accommodate the 10 2 wire needed for the 5000-watt 240-volt heater.
What wire size is needed for 30amp load for 34 feet on 12 volts DC?
For a 30 amp load at 12 volts DC over a distance of 34 feet, a wire size of at least AWG 8 would be recommended to minimize voltage drop and ensure efficient power delivery. It is important to consult with local electrical codes and standards to ensure compliance with regulations.
If you can feel an electrical current when you touch old conduit lines in the attic, it's important to turn off the power at the circuit breaker before attempting to replace them. Once the power is off, you can replace the conduit lines using new wires following the color coding standards - typically, black is used for hot wires and white is used for neutral wires in residential electrical systems. However, it's always advisable to use a voltage tester to confirm which wire is carrying the current before starting the replacement.
Answer for USA, Canada and countries running a 60 Hz supply service.
No.
A disconnecting means must be
1. Within 50 feet.
2. Within sight of.
3. Readily accessible.
A breaker with a breaker lock out installed is simply not readily accessible.

What is amp rating 32 gauge wire?
In my experience there is no such thing as 32 gauge wire. If it existed it would be so small as to be breakable by 2 fingers, probably the size of a human hair or smaller.
I'm using 32 gauge wire in a project of mine. The amp rating can be found at the link below.
OK, I stand corrected. It certainly is not a wire listed in the NEC. According to the reference mentioned above, 32 gauge wire would carry 0.53 amps in free air and 0.32 amps in conduit.
Please note: that the amperage capacities in this chart do not align themselves with either the CEC or the NEC electrical code books.

Answer for USA, Canada and countries running a 60 Hz supply service.
Yes, a 40 amp breaker can feed a 100 amp rated sub panel. The #8 wires are appropriate and the 4 wires consist of 2 hots, a neutral, and a ground. As a sub panel you keep the grounds and neutrals isolated from one another. If you are unsure of how to do this, consult a licensed electrician.

How do you hook up a range outlet with one red wire one black wire and one white wire?
There should be 3 insulated lugs in the dryer, two hots and a neutral. Connect the red and black wires in your new cord to the hot lugs (red & black are interchangeable), and the white neutral to the neutral lug. Neutral is the center wire on your older 3-wire cord, and should be a silver screw. Connect the green ground wire directly to the chassis of the sryer using a convienent screw. Use the four prong cord if you can. It is safer because it has the extra ground wire which older cords did not. If the neutral lug is bonded to the chassis, break that bond. It is for older 3-wire cords and is not needed with your modern 4-wire cord. Also, see the question "Is it possible to put a 4-prong plug on a dryer that uses a 3-prong plug and how would you do this?" It is a very similar question with more answers.
A 250 kcmil copper feeder cable would be appropriate for a 300 amp circuit breaker when stepping up from 220V to 380V. It is always recommended to consult with a qualified electrician or engineer to ensure the correct cable size for your specific application and wiring conditions.
How many watts in 120v 1.7 amp motor?
Answer for USA, Canada and countries running a 60 Hz supply service.
I think the answer you are looking for is 204 volt-amps. In a light that would be 204 Watts but since a motor doesn't use Watts it is simply called volt-amps.
I don't mean to confuse you. Calling it 204 Watts would certainly be understood.

Just firmly connect the wires under the screws and that will couple them.
Each outlet has two hot and two neutral screws; just connect the wires appropriately and make certain that the outlet is properly grounded.
What size rigid conduit for 400 amp service?
For a 400 amp service, you would typically use a minimum of 3-inch rigid metal conduit (RMC) to accommodate the large conductors required for that amperage. It's essential to consult local electrical codes and regulations to ensure compliance with sizing requirements for your specific installation.
Why are motion sensing lights sustainable?
Motion sensing lights are sustainable because they only activate when motion is detected, thus reducing energy consumption compared to lights that remain on constantly. This feature ensures that energy is not wasted on lighting areas that are not in use, leading to cost savings and a lower environmental impact.
How many volts is 2 gauge 200 amp 3 ohms?
Ohm's Law states Volts = Amps x Resistance.
You would need to apply 600 volts across 3 ohm load to have 200 Amps flow in circuit.
Not sure what you are really asking and why you mentioned 2 gauge.
What size aluminum ser cable needed for 100 amp sub panel?
For a 100 amp sub panel, you would typically need a 2-2-2-4 aluminum SER cable. This cable consists of three insulated conductors (two hot and one neutral) and one bare ground wire. It is important to always consult your local electrical code and a qualified electrician to ensure you have the correct size and type of cable for your specific installation.
Who makes a main breaker 200 amp service that has built in 200 amp gfci?
Currently, there is no manufacturer that makes a main breaker 200 amp service with built-in 200 amp ground fault circuit interrupter (GFCI) protection. GFCI protection is typically provided through individual GFCI outlets or circuit breakers installed within the electrical system.

Turn off the branch-circuit circuit breaker on the service panel. Remove the switch cover plate. Check to make sure that the power is off by turning on the non-contact voltage tester and bringing it near the wires in the box. If there is voltage still present on the wires, the tester will beep loudly. Some boxes have more than one circuit running through them. You may have to turn off more than one circuit breaker before you can work on the circuit safely.

Remove the two #6-32 screws holding the switch in the box. Pull the switch out of the box and disconnect the wires from the switch. Remove the wire nut holding the two white wires together. You may have to use the Lineman's pliers to untwist the white wires once you remove the wire nut to separate them.

Separate all the wires so that they do not touch one another or the box. Turn the branch-circuit circuit breaker on temporarily. Use the non-contact tester to ascertain which black wire is bringing power to the box. Fix the position of that wire firmly in your mind and turn the circuit breaker off again.

Cut the white wire flush with its insulation and remove 3/4 of an inch of insulation from the cut ends with the wire strippers. Cut a 6 to 8 inch length of white wire, removing 3/4 inch of insulation from both ends. Make a 3-way splice with the two white wires in the box. Hold the stripped ends of the wires side by side and twist them tightly together in a clockwise twist with the Lineman's pliers. Complete the splice by screwing on a wire nut. Form a loop, in the free end of the white, pigtail wire.

Connect the black wire bringing power to the box to the side of the switch receptacle with the double brass screws joined together. Connect the black wire going to the light to the single brass screw on the opposite side of the switch. Connect the white wire to the silver screw and the bare copper wire to the green, octagon-shaped screw. Place the loops around the screws in a clockwise direction and tighten the screws.

What does 12 amps resistive load mean?
A resistive load just describes something like a toaster, electric water heater or space heater, where the load is relatively constant. The description is used to distinguish from something like an electric motor, which uses much more current at startup then drops off significantly after it is running.
AnswerIn a.c. circuits, a resistive load describes a load whose load current is in phase with its supply voltage. Expressed another way, it is a load having unity power factor. Resistive loads are not necessarily constant -for example a tungsten-filament lamp has a low resistance when cold and a high resistance at its operating temperature.
How much wattage is available in a 15amp breaker?
A 15-amp breaker can handle a maximum load of 1800 watts (15 amps x 120 volts). However, it is recommended to only load a circuit up to 80% of its capacity, so in practice, you should only use up to 1440 watts on a 15-amp breaker.
Can you put a 50 amp beaker in a 60 amp panel?
I've never heard of a 50 amp b-e-a-k-e-r. You can put a 50 amp b-r- e-a-k-e-r in a 60 amp panel; but you can only have an additional 10 amp breaker along with it. You may need to consider adding another larger panel or a separate 50 amp breaker box.
How is a plug in receptacle connected to other receptacles in a normal house circuit?
There are typically 8 to 10 receptacles on most house circuits with special applications in Kitchens. The wires are in parallel with Black to Black, White to White and Bare Wire Ground to Ground.
How should old 3 wire stove be wired in panel bare wire to neutral or ground or both?
The bare wire from the old 3-wire stove should be connected to the grounding terminal in the panel. The neutral and ground should not be bonded together at the stove. If the stove requires a 4-wire connection, it's best to run a new 4-wire circuit to meet current electrical codes for safety.
If this is a regular incandescent fixture, the manufacturer probably just used white wire for cost reasons.
Before you connect the fixture's wires you should take a close look at the fixture and make sure that the wire that goes to the shell of the bulb socket is connected to neutral wire (usually the white wire in the ceiling box) and the wire that is connected to the center of the socket goes to hot (usually the black wire in the ceiling box).
If this is a fluorescent or hid (metal halide or sodium vapor) lamp fixture, please consult the directions or contact the manufacturer for installation instructions.

Why do some electric panel have ground and neutral bonded together?
Some electric panels have the ground and neutral bonded together for safety reasons. This bonding can help prevent dangerous voltage levels and reduce the risk of electrical shocks in case of a fault. However, it is important to check local electrical codes and guidelines before making any modifications to ensure compliance and safety.
