Calculations
1.
To determine the AWG size wire necessary for a specific connected load to maintain the proper voltage
E
for each miscellaneous lighting visual aid, use the above table and Ohms Law
I
=
as follows:
R
a. Example. What size wire will be necessary in a circuit of 120 volts AC to maintain a 2 percent voltage
drop with the following connected load which is separated 500 feet from the power supply?
(1) Lighted Wind Tee Load - 30 lamps, 25 watts each = 750 watts.
watts 750
(2) The total operating current for the wind tee is
I
=
=
=6.25<i>amperes
.
volts 120
(3)
Permissible voltage drop for homerun wire is 120 volts x 2% = 2.4 volts.
(4)
Maximum resistance of homerun wires with a separation of 500 feet (1,000 feet (305 m) of wire
E
2.4 volts
used) to maintain not more than 2.4 volts drop is
R
= =
= 0.384<i>ohms
per
I 6.25 amperes
1,000 feet (305 m) of wire.
(5)
From the above table, obtain the wire size having a resistance per 1,000 feet (305 m) of wire
that does not exceed 0.384 ohms per 1,000 feet (305 m) of wire. The wire size that meets
this requirement is No. 4 AWG wire with a resistance of 0.2523 ohms per 1,000 feet (305
m) of wire.
(6)
By using No. 4 AWG wire in this circuit, the voltage drop is E=IR=6.25-amperes x 0.2523
ohms=1.58 volts which is less than the permissible voltage drop of 2.4 volts.
2.
Where it has been determined that it will require an extra large size wire for homeruns to compensate
for voltage drop in a 120-volt power supply, one of the following methods should be considered.
a. A 120/240-volt power supply.
b.
A booster transformer, in either a 120-volt or 120/240-volt power supply, if it has been determined
its use will be more economical.
