From a consumer standpoint, the weakest point of coaxial cable is its vulnerability to signal quality loss during use. Factors that determine the magnitude of the signal loss include the length of the cable, wear on the wire and exposure to sources of electromagnetic interference from other electronic devices.
It is not safe to plug one power strip into another. This is called piggybacking or daisy chaining, and it creates an electrical fire hazard that could prove to be catastrophic.
According to the Star Tribune, a double tap occurs when two conductors are connected under one screw inside a panelboard. Most circuit breakers do not support double tapping, although some manufacturers, such as like Cutler Hammer, make hardware specially designed for this purpose.
Not all jurisdictions require a person to hold a license to perform electrical work, according to the Copper Development Association. Therefore, a non-electrician could potentially perform wiring for another person. A homeowner is typically able to complete minor wiring installations and repairs in a home with necessary permits and inspections.
Estimate the amount of solar panels needed to satisfy the electrical power usage of your home by dividing your average daily energy use by the amount of solar resource available to your region and multiplying that number to adjust it for the efficiency of your panel. Gather your utility bills, and by using a computer, it takes about 30 minutes to calculate the amount of solar panels you need.
The color of wires is dependent on the method of wiring and where one is located. In the United States, a common two-wire ungrounded circuit has a red positive wire and a black negative wire.
A fuse prevents an electrical object from receiving too much current. In the event too much electricity is received by an electrical component, the fuse is designed to melt and separate.
While solar energy is used worldwide and even in space, the country with the most installed solar capacity is Germany. According to the European Photovoltaic Industry Association, Germany had approximately 35 GW of installed solar capacity by the end of 2013, almost double its closest competitor. China, Italy, Japan and the United States round out the top five countries with installed solar capacity.
Fluorescent light fixtures are produced for both hard ceiling and drop ceiling installations. Installation techniques are different for each type. These instructions focus on installation of fluorescent light fixtures in regular ceilings, with attachment to the framework by wood screws. The process is likely to take an afternoon.
The first step in basic electrical wiring or splicing is to turn off the power to the area in which work is being completed. To ensure safety, it is also important to use a junction box when adding new wires or splicing existing wires.
Exposure to moisture or cold can cause a light bulb to explode. Failure of a light bulb may also be the result of tight screwing or too much electrical flow.
Consumer and small commercial electrical lines must be buried between 6 and 24 inches underground, while large commercial and industrial lines must be buried between 30 and 36 feet underground. Electrical lines for carrying current to a home or building must be buried deep enough to avoid digging accidents by homeowners and others.
A Christmas light fixer is a tool for repairing Christmas decoration lights that won't light up. It is a dedicated tool that features a voltage detector, fuse and bulb testers, bulb remover and a shunt repairer. This tool is available in different designs and colors to suit customers' needs.
In order to wire a home light switch you need wire cutters and wire nuts. Start by turning off the power from the circuit breaker, then remove the switch plate, strip and connect the wires and place the new switch in the box.
Uninterruptible power supplies work by converting battery power to power that can be used by the computer system. A computer system plugs into the uninterruptible power supply, which then plugs into a wall outlet. If the power goes off or the voltage running to the computer system fluctuates, the uninterruptible power supply maintains a steady stream of acceptable power to the computer system.
A conductivity meter is used to measure the ability of a water-based solution to carry an electric current. It can also evaluate the salinity levels of surface water and soil samples, as well as measure pH.
A 12-gauge wire can carry between 15 and 20 amps for normal electrical wires. When wiring chassis, 12-gauge wire can carry a maximum of 41 amps along the metal conductor. The conductive part of a 12-gauge wire is 0.0808 inch in diameter. This gauge is found in extension cords.
Cover a protruding outlet with a deep cover for the specific type of outlet. If possible, consider buying a thinner outlet instead of covering the protruding one.
Square D offers 11 different categories of electrical circuit breakers and related products through Schneider Electric, including miniature, molded-case, mission-critical, universal-power, direct-current rated, thermal magnetic and medium-voltage circuit breakers. The company also makes enclosures, ground-fault protection products, motor-circuit protectors and supplementary protectors.
Adding a new breaker to a home's main electrical panel is relatively easy even for someone with limited electrical experience. With just a flashlight and a screwdriver, you can easily add a 60 amp breaker to an electrical panel in 10 or 15 minutes.
In the United States, home wall outlets carry a voltage of 120 VAC, or voltage from alternating current. This is the standard amount, but some heavy-duty appliances require higher voltages.
