Modification of Old Electrical Work

The normal colors of a residential outlet are black(hot), white(nuetral), and bare/green(ground). It is common to 'feed thru' an outlet, in other words to bring the power in on one trio of wires tied to the outlet and send it out on another trio of wires also tied to the outlet. If however one white wire is not connected the power will not feed thru properly and whatever outlets are downstream will not work. It is possible to burn up whatever equipment is plugged into the downstream outlets, espiecaly if it is electronic ie; omputers, video equipment etc... Hope this helps. Remember turn off power before working all electrical outlets.

To calculate the amperage, you can use the formula A = W / V, where A is amperage, W is watts, and V is voltage. Thus, for 4800 watts at 220 volts, the amperage would be 21.82 amps.

A contact device installed at an outlet for the connection of an attachment plug is called a receptacle or socket. It provides the electrical connection point for portable devices to plug into and draw power from the outlet.

In the US a miniature circuit breaker, sold in a single unit, is about 15$, about the same as a regular breaker. If sold as a double unit, meaning two mini breakers installed into one housing, then it is about 25$.

The screw is actually only silver in color and it is where the neutral wire(s) get connected to, (white wire). the gold colored screw gets connected to the positive(black or red) wire(s). Green screw is for ground wire.

The size of the amp breaker for a 220V air conditioner will depend on the specific requirements of the air conditioner. As a general guideline, you can calculate the required amps by dividing the air conditioner's wattage by the voltage (220V). For example, if your air conditioner is rated at 5500 watts, you would need a breaker of at least 25 amps (5500 watts / 220 volts = 25 amps). It is always best to consult the manufacturer's specifications or a licensed electrician to ensure the correct size breaker is installed.

The crackling sound indicates a potential electrical issue, possibly with faulty wiring or a loose connection. Continuing to turn on the breaker could pose a fire hazard. It is recommended to have a qualified electrician inspect and repair the issue to ensure safety.

Appliances are rated in watts to indicate the total power they consume, which is the product of the voltage and current they draw (P = V x I). Some appliances may also be rated in amps, which measures the current they require from the power source. Both ratings are important for determining electrical loads and ensuring safety.

When a 3 prong electrical outlet tester indicates an open ground, it is telling you that the d shaped slot on the outlet is: not connected to the ground conductor ( the bare or green jacketed wire that is supposed to provide an electrical connection to the earth) or that if it is connected to the designated ground wire the wire itself is not connected to the earth or perhaps there is no ground conductor available in the electrical device box where the outlet is located. Many areas of the country did not require that a ground conductor had to accompany the hot and neutral conductors in electrical devise boxes until somewhere around 1960 or so and some areas didn't adopt that requirement until several years after that. If there is no ground wire in your devise box you are out of luck and you should install an old style 2 prong outlet to prevent use of appliances that require a ground or you should run modern wiring to the location. If you are asking this question it means that you don't have a basic understanding of electrical wiring. It would be prudent to consult someone who has that knowledge to assess and guide you before you attempt to correct the situation.

A fuse is an overcurrent protection device. So the fuse fitted inside a plug is designed to protect the circuit which it supplies. British plugs are rated at 13 A, but must be fitted with an appropriately-rated fuse, based on the load supplied from that socket.

If the electrical box is grounded, check with a tester, the "hot" wire will have a voltage to the the grounded box the neutral wire will not. If the box is not grounded, with the breaker supplying the voltage turned off, use a tester on the resistance scale to check for continuity between the wires and a cold water pipe or some other grounded medium. The neutral will have continuity between the wire and a ground the "hot" wire will not.

To determine the correct size circuit breaker for a well pump, you should check the manufacturer's recommendations on the pump's label or in the manual. Typically, most well pumps require a 15-amp or 20-amp circuit breaker for residential use. Make sure the breaker is appropriately sized for the pump's power requirements to avoid damage or safety hazards.

Amps (A) measure electrical current flow, while volt-amps (VA) measure apparent power in an electrical circuit, which is the combination of both real power (measured in watts) and reactive power. Essentially, amps refer to current, while volt-amps refer to total power.

You can certainly use the larger breaker panel provided that you sub-feed the panel using breakers that do not exceed the rating of any down-stream device.

If you have any concerns or do not thoroughly understand what you are doing, contact a qualified electrical contractor in your area.

For a 100A circuit breaker, you typically need a wire size of #2 AWG (American Wire Gauge) for copper conductors or #1/0 AWG for aluminum conductors. It is important to consult the National Electrical Code (NEC) or a qualified electrician to determine the appropriate wire size for your specific installation.

For controlling light fixtures from four different locations, a combination of three-way and four-way toggle switches would be used. Three-way switches are used in conjunction with four-way switches to allow multiple locations to control a single set of lights.

To calculate the gauge of wire based on current carrying capacity, you can use the American Wire Gauge (AWG) standard. The AWG table provides a reference for selecting the appropriate gauge wire for a given current rating. Choose a wire gauge that can safely carry the expected current without overheating. It's important to consider factors like wire length, insulation, and ambient temperature when determining the appropriate wire gauge for a specific application.

Most dryers do not have internal circuit breakers, but they DO have "high temperature" sensors that shut down the heating element. Often motors will also have a shut-down feature that prevents internal damage.

A Wii console typically uses around 1.5 amps when running at full load. It's always a good idea to check the specific power requirements listed on the device or its power adapter to ensure you have the correct amperage for your setup.

Some airplanes do. See the related link on Continental Airlines, that I've provided. I'm not sure about other airlines. Some of the planes provide electric outlets which require an adapter. Years ago, I remember most planes had an outlet in the lavatory, which I believe was just for electric shavers, as I think the power source was not stable enough to run electronic devices.

A par 38 light fixture is a type of spotlight commonly used for directional lighting in residential, commercial, and outdoor settings. It accommodates a parabolic aluminized reflector (PAR) 38 bulb, which produces a focused beam of light with a specific angle that can be adjusted to suit different illumination needs.

The answer depends on what type of access you have to the junction box. The wire external to the box may have some slack that can be brought into the box. If everything is tight you will probably have to install one or more additional junction boxes or rerun wire from electric panel.

As an example assume that the short wire has no external slack, but you can install a new junction box near the other box and in the path of the short wire.

1. Pull the short wire from existing junction box.

2. Install new box in path of short wire so more slack will be available in the additional junction box; and pull wire into new box.

3. Run a wire of the same size from new to old box and re-splice any connections for original short wire or new connections; and connect this new wire to the original short wire in the new box.

Make sure you follow all code requirements for your locale.

If there is a brass colored screw and a silver colored screw, the BLACK wire will connect to the brass screw.

If you can't see a difference, connect the black wire to whichever screw connects to the CENTER contact of the light fixture.

For a 30 amp circuit running 100 feet, you would typically need to use at least a 10-gauge wire to ensure safe and efficient electrical flow. It's important to consult local building codes and regulations to ensure compliance.
