ssed in a certain number of lamps. The
following table will be of assistance in determining the size of the
battery required:
Watts Equivalent Number
No. Type of Appliance Consumed of 20 Watt Lamps
--- ----------------- -------- -----------------
1 16 candle power, Mazda lamp 20 1
2 12 candle power, Mazda lamp 115 3/4
3 Electric Fan, small size 75 4
4 Small Sewing machine motor 100 5
5 Vacuum cleaner 160 8
6 Washing machine 200 10
7 Churn, 1/6 h.p. 200 10
8 Cream Separator, 1/6 h.p. 200 10
9 Water pump 1/6 h.p. 200 10
10 Electric water heater, small 350 18
11 Electric toaster 525 26
12 Electric stove, small 600 30
13 Electric iron 600 30
14 Pump, 1/2 h.p. 600 30
From the foregoing table we can determine the current consumption of
the various appliances:
Amps at 32 Amps at 110
No. Watts Volts Volts
--- ----- ---------- ------------
1 20 0.625 0.18
2 15 0.47 0.14
3 75 2.34 6.80
4 100 3.125 0.90
5 160 5.00 1.44
6 200 6.25 1.80
7 200 6.25 1.80
8 200 6.25 1.80
9 200 6.25 1.80
10 350 11.00 3.20
11 525 16.4 4.77
12 600 18.75 5.40
13 600 18.75 5.40
14 600 18.75 5.40
The following tables show how long the battery will carry various
currents continuously:

Location of Plant
The various appliances should be placed as near to each other as
possible. The lights, of course, must be placed so as to illuminate
the different rooms, barns, etc., but the power devices should be
placed as close as possible to each other and to the plant. The
purpose of this is to use as little wire as possible between the plant
and the various appliances so as to prevent excessive voltage drop in
the lines.
