Volts cause current to flow through the load. The current is measured in amps, and the volts multiplied by the amps gives the power in watts.

What is the difference between full load amps and running load amps?

Full load amps is the maximum rated amps that the motor should draw according to its nameplate rating. Running load amps is the actual amperage the motor is drawing at that point in time when the test is taken. Some motor loads vary depending on if the load is cyclic. The reading on this type of motor would be from no load amps to full load amps.

How do you calculate the load in a power distribution line?

How do you measure amperes?

You use an 'amp gauge' to measure amps in an actual circuit. It is hooked in series with the load. It can be placed anywhere in the circuit as long as it is hooked in series. Mathematically, you have to know the resistance, or wattage and voltage of a circuit. Volts=amps*resistance or amps=volts/resistance, or resistance=volts/amps. Ohms law!

To answer this question a voltage needs to be stated. Wire is sized by the amount of amperage the load takes. W = Amps x Volts. Amps = 650/ volts.

Watts To Amps

Volts Amps Watages How Do I Calculate The Max Distance In Excel

The reason different wire lengths bear different ratings is because the electrical resistance builds up as the cable gets longer. At that point, up-sizing the power cable will restore the voltage to its intended level.

Undersizing the wire size will result in excessive power (watts) being lost in the wires rather than delivered to the load (battery bank, inverter. Typically we recommend the power loss below 5%.

A 5% voltage drop causes an approximate 10% loss in light output. Voltage drop causes a nearly proportional drop in light output. A voltage drop greater than 5% will reduce this necessary voltage difference, and can reduce charge current to the battery by a much greater percentage. Our general recommendation here is to size for a 2-3% voltage drop. If you think that the PV array may be expanded in the future, size the wire for future expansion.

On the other hand, installing too large a wire gauge doesn't really have a downside, but there is the potential for better performance. Obviously, there's no need to buy 2-gauge wiring when 10-gauge will do. That kind of overkill would be a waste of money. But if the calculator could lean either way between two sizes, going with the larger wire size would be the smart choice.
