How far are electrical services required to be from windows on a residential home in USA?
In the USA the National Electrical Code prohibits the "point of attachment" of an overhead electric service to be within 36 inches of an openable window, doorway, or porch... in other words they do not want a person to be able to reach out of a building opening and be able to touch exposed live power wires. I believe this rule applies to all buildings not just residential. The "point of attachment" is the area near the top of the building's electrical conduit where the building wires are spliced to the utility company wires. This is the only area where there should be exposed power wires. There is no distance limitation from windows and doors for the remainder of the electrical service that has no exposed power wires, such as the conduits, meters, panels
Can two separate wires in parallel be used to increase the amperage capacity?
Yes they can but the electrical code states that the wires can only be 1/0 AWG and larger.
What is conduit fitting?
Conduit fitting is used on metal pipes that house electrical wires. These fittings are not only to connect the various pieces together, but to keep a relatively water tight seal to the wires.
Why don't we use silver electrical wires?
We don't generally use silver electrical wires because silver costs more than copper and is only marginally better as a conductor. Economics and practicality dictate our choices here. Copper is a much more common metal than silver.
Why will too many electric devices operating at one time often blow a fuse or trip a circuit breaker?
In a house, usually all the outlets in a room are on one breaker or fuse. Each thing plugged into those outlets consumes some electrical power. This is a number rated in Watts. In this case, the more Watts something consumes, the higher the current is (measured in Amps) in the wires that connect the outlets to the main power in the breaker box. The current in power circuit must be limited for safety reasons. The wires in the walls can only handle a certain amount of current safely. If too much current flows the wires can become extremely hot, possibly starting a fire.

What is the only thing that can use power in an electrical circuit?
The load that is connected to the circuit is what draws the power of the electrical circuit.
How do you remove the wires of a power side mirror Wires are the only thing connecting the broken mirror would it be bad to cut them 2001 Honda Civic?
The electrical connection could possibly be inside the door panel. I would not advise just cutting the wires ... this could lead to a dead short if the two wires got crossed together.
How can I replace my laptop's power cord.?
Fix your laptop power cord that hasn't been supplying consistent power. some basic tools, electrical tape, and the perseverance that only a true cheapskate can muster. I performed this on my very own HP Pavilion's power cord and adapter.

Yes they can but the electrical code states that the wires can only be 1/0 AWG and larger.
Are over head electrical wires a problem?
Only if you touch them :) Some believe the electro-magnetic energy from power lines may cause cancer. Most are concerned with overhead power lines when needed to trim trees, or access other elevated areas.
What type of power tools do not use a chuck?
A chuck is ONLY used on a drill, so ALL other power tools do not use a chuck.
What is the difference between hand tools and power tools?
Hand tools are devices for performing work on a material or a physical system using only hands while the power toolsare tools powered by an electric motor Hand tools are devices for performing work on a material or a physical system using only hands while the power tools are tools powered by an electric motorHand tools use hands and power tools use power.a power tool is an electric tool like a band saw or circular saw, a hand tool is a non electric one like a file or hammerHand tools you use your hands and power tools you use power like air or electricity
Where do I find the wiring diagram for the fuel pump on a 1979 Dodge Power Wagon?
the 79 dodge powerwagon only had a mechanical fuel pump. so unless someone added a after market electrical one. it should not have wires
Does a Princess phone need electrical power or only a jack?
Only a phone jack.
What is a Black and Decker?
A Black and Decker is a generic name for any type of electrical power tool, whether it is one made by the Black and Decker company or not.
When discussing electrical current what does DC stands for?
When discussing electrical current, DC stands for Direct Current (a current where the electron flow in the wires goes only one way)
