The results show that the cost <strong>of</strong> distribution copper for<br />
the 125 volt system is $968,22 as compared with |453,58 for the three<br />
wire system.<br />
The other factors, entering into the cost <strong>of</strong> the complete<br />
plant, which would be affected by the system <strong>of</strong> distribution, are tab-<br />
ulated below in Table No. 5.<br />

The above tabulation shows a saving <strong>of</strong> $429.74 which<br />
could be effected by the use <strong>of</strong> the three wire system. The additional<br />
labor required to install the third wire has not been included in the<br />
above estimates, for this item at beat is pure conjecture. The prob-<br />
abilities are that the comparitive ease <strong>of</strong> handling #5, 6 and 8 wire<br />
instead <strong>of</strong> the l/o and 2/o wire (necessitated in large quantities by<br />
the 100 volt system) would nearly equalize the labor requirement <strong>of</strong><br />
the two systems.
