HOW TO ESTIMATE THE COST OF ELECTRICAL EQUIPMENT Q
Table l contains il list of electrical appliances lor the liarm loat
home, with approximate price and kilowatt-ho11r consumption old tent
each. Table 2 contains a list ol electric equipment used on the the
farm outside the home and the horsepower requirement and our- j
rent consumption ol each, per unit ol capacity. This information Um,
sho11ld be helpful in considering the purchase ol such equipment. (uk
Altho the amount of electricity required for operating any macliiug mm
varies with the conditions under which it is operated. the prospee
tive purchaser may estimate the approximate cost ol current lor -·
operating each device by multiplying the kilowatt—hour consump»
tion figures given by the local rate charged lor electricity. AI,
HOW TO ESTIMATE THE COST OF USING ELECTRICAL POWER
The kilowatt hour (kw. hr.) is the unit ol measure by which agi
electricity is purchased just as a bushel is the 11nit [or nieasttriug Wag
. grain. For example, a 100-watt light bulb operating [or I0 hours Flag
uses a kilowatt ho11r of electrical energy. The number of hours SIE]
an appliance may operate on l kilowatt hour ol current is deter- Refr
mined by dividing the number of watts required to operate it into FEE?
l000. .=\ 500—watt flatiron used continuously will operate 2 hours Milk
(1000+500 ; 2) on l kilowatt of electrical energy. Electricity 60
used is recorded by an instrument known as a watt—ho1u‘ meter. To FEB
estimate the cost of using electricity, proceed as follows: U TY
l. Make a list of the appliances to be used and tl1e amount ol —
current used by each. The probable consumption, in kilowatt
hours, ol each appliance may be taken [rom Tables l and 2. 1]];,1

 The Cost of Electricity for I/te Frtrmslead 5
Many contracts lor electric service provide special "oll peak
trni load" rates [or storage-type water heaters. The rate is about one
ol cent per kilowatt hour. The “oll peak load" period is at night when .
the the demand l`or current lor other purposes is small.

title rates.

Formerly No. 14 wire was used almost exclusively for residence
branch circuits but owing to the increasing variety of electrital
appliances used in the home, No. l2 wire is reconnnended. Ranges.
water heaters, and some motors require larger wires, the sizes ol
which must be determined. For further inlorination consult your
county or home agent, or write to the Extension Division, College
of Agriculture, Lexington, Kentucky.
