Calculations and allowable
voltage drop are based on
revised UL 1971 & 464 standards
for current and limits.
End of Line method uses only the wire guage for the first device to source for calculation
Standard Wire Resistance in Ohms per 1000 feet @ 27 C.
This circuit is sourced from:
Notes:
Wire resistance is doubled in the calculations for two wires (Positive and Negative)
The voltage calculated to the last device in any method must not be lower then
the manufactures listed minimum operating voltage (IE: rated operating voltage16-33 VDC).
