Feeders Takeoff

Important

Complete pre-takeoff-research, including wiring-method-selection, before beginning takeoff.

Execution

Primaries
Secondaries
Feeders
Grounding

Formatting

All feeder takeoff descriptions should be prefixed with <parent> TO <child>

It is acceptable to use typicals for identical feeders (i.e. meter centers fed from bus plugs) so long as the typical is in Area = "01 - Feeders/Risers ...".¹

Routing

Run parallel to building lines and route through corridors where possible.

Important

All takeoffs in Systems with names including "site" should be in "Site" Area, Phase, and Bid Item breakdowns.

For adjacent panels, use a minimum 10ft length.

Adders

Use the difference in elevation between equipment or 10ft, whichever is greater.

Add an additional 5ft (total 15ft) for site runs (primaries, secondaries, etc.).

Primaries

Area = "2 - Site"
Phase = "Site"
System = "PRI - Primaries"

Usually only empty conduit if included.

Secondaries

Area = "2 - Site"
Phase = "Site"
System = "SEC - Secondaries"

Wiring on Vault Racks

Where secondary conductors run on racks in utility vaults manually set the length of conduit, measure the wire length, add 20ft in addition to previously mentioned adders.

Feeders

Area = "01 - Feeders/Risers Building"
Phase = "Feeders"
System = "FRR - Feeders and Risers"

[!info] Garage Feeders Area "01 - Feeders/Risers Garage" is seldom used. It may be appropriate for totally separate parking garage buildings. Seek clarification before using.
