Requirement Precedence

In case of conflict:

Requirements of the plans and specs are superseded by the terms of our proposal, which are superseded by specific direction from the bid team.

Wiring Method Selection

See wiring-method-selection.

Voltage Drop

Unless explicitly stated in the plans or specs, conductors are to be sized according to the relevant schedule, without respect for voltage drop.

Feeders and Unit Subfeeds

Branch Circuits

If voltage drop is to be considered in takeoff, Use the table provided in the drawings. If no table is provided, use the following:

Wire Size	Max Length
#12	100ft
#10	200ft
#8	>200ft

Wiring Device Selection

Wiring devices and their wall plates are a common target of gold-plating.
