- Editor's Notes
- [Enclosure]:#### chart of 2-wire, 3-wire, 4-wire, 5-wire, 6-wire, and 7-wire systems to compare costs with 2 wire system.####[handwriting at bottom]: The pencil figures of the amendments introduced by taking into account the fact that feeders have only 33% of their outsides in their –entrals and that 60% of the copper in a system is generally speaking put into the feeders for 10% and 1% drop. Similar proportions might be presumed to hold for systems with more than 3 wires and in fairness the principle should be retained. On his own premises however Mr. Leonard appears to be correct.####[name mentions: H. Ward Leonard]
