Electrical Takeoff

Important

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

Tip

Use heating-designations for uncertain scope.

Garage

In conventional slab garages, use ENT and PVC as permitted.

In precast slab garages, use EMT.

Receptacles

Floor Boxes

COMMON ASSEMBLIES/FLOOR BOXES/...

Use suitable floor box assembly, delete floor box items, add ITEM DATABASE/WIRING & SYSTEM DEVICES/FLOOR BOXES & FITTTINGS/GENERIC - FLOOR BOXES & ACCESS/POKE-THRU W/ DUPLEX RECEPTACLE

Homeruns

Lighting Homeruns

  • Area = "XX - Level XX Building"
  • Phase = "Building - Back of House (BOH)"

Takeoff homeruns in Building breakdowns, even where serving Amenity spaces.

Mechanical Connections

Stair Pressurization Fans

Assume branch circuit conductors must be protected per fire-resistive-wiring-methods-takeoff.

Roof Mounted Equipment

Unit Condensing Units

Put homeruns on the Area of the dwelling unit. Put connections on the Area of the CU.

.../CU CONDENSER SLEEVE W/ FLEX - NO HMRN WIRE

NO SLEEVE: Routed through a "doghouse" (a large weatherproof opening) with several other feeds. Used where drilling openings for individual sleeves would be impractical.

PVC SLEEVE, EMT SLEEVE: Routed up through the roof, (optionally through a disconnect) with flex to the equipment.

Equipment Racks
