amperage loss in junction box When electrical current moves through a wire, it is pushed by electrical potential (voltage) and it needs to surpass a certain level of contrary pressure caused by the wire. The voltage drop is . I bought and installed new juction boxes for the individual rooms. I was suprised to learn that there is not a ground screw that comes with the junction box. Rather than paying for a pre-made pigtail with a green screw, am I allowed to use any screw that fits?

how to reduce amperage loss
What it means: Because a junction box houses the splices where wires are connected to one another, a person could inadvertently damage the wires or get a shock. .Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run. When sizing conductors, calculations limits wire size to voltage drop and NEC ampacity. Southwire's Re 3TM Voltage Drop Calculator is designed for applications using AWG and KCMIL sizes only. How to calculate voltage drop, you ask?When electrical current moves through a wire, it is pushed by electrical potential (voltage) and it needs to surpass a certain level of contrary pressure caused by the wire. The voltage drop is the amount of electrical potential (voltage) loss caused by the contrary pressure of the wire.
To calculate amperage loss using Ohm’s Law, you will need to know the resistance of the conductor, the length of the conductor, and the voltage applied to the circuit. The resistance of the conductor can be found using the following formula:Enter the information below to calculate voltage drop across a circuit. Voltage - Enter the voltage at the source of the circuit. Single-phase voltages are usually 115V or 120V, while three-phase voltages are typically 208V, 230V or 480V. Amperes - Enter the maximum current in amps that will flow through the circuit.You want to transmit 1800W, which is 15A at 120V through a distance of 500' using a wire which has resistance of 1 Ohm. The power lost to heat in the wires in this case will be 15^2 * 1 = 225W. So you put 1800W in at the source but you only get 1575W at the load. Now say you bump up the voltage to 480V. What about running a 6-2 gauge wire to the center attic in a junction-box, then branching from that using 10-2 to all 4 exterior receptacles? Will that meet NEC code if i drop it in conduit from lintel-level to receptacle box? Again it depends on your location. You need to check the local codes.
Sounds like you have a bad connection somewhere, and a potentially very dangerous situation -- if you have a 10A load and a 40V voltage drop, that means that 400W is being dissipated somewhere, possibly in a junction box somewhere in your house, the meter, or somewhere in the power company's circuit, so it's a serious fire hazard.
There are numerous voltage drop calculators on line that will tell you the voltage drop for the wire gage and distance of run. Amps is the same for the entire circuit no matter how long the circuit is. It does not change over distance. .
Advice on wiring electrical junction box with easy to follow junction box wiring diagrams, including information on 20 and 30 amp junction boxes. Be sure which type of junction box should be used for ring main, radial circuits and lighting circuits. Also includes safety tips and information on fixing junction boxes and ensuring they are accessible. When conductors come into a junction box in one raceway and exit the box in another raceway (not a straight pull) of a different size, how much distance do you need between those raceways? You need six times the trade size of the larger raceway.
