# 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.

## Lighting Control

See [[lighting-controls-takeoff]].

## Receptacles

## Floor Boxes

`COMMON ASSEMBLIES`/`FLOOR BOXES`/...

### Poke-Thru's

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

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

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

## Mechanical Connections

`COMMON ASSEMBLIES`/`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.

.../`CONDENSOR HOME RUNS`

.../`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

Max 20 disconnects per rack

`DISTRIBUTIION`/`TRAPEZE RACK SUPPORT ...`/`...`

### Trash Chute

1. **Horizontal:**

    `COMMON ASSEMBLIES`/`MECHANICAL CONNECTIONS ...`/...
    * **Length** = Length per drawings, 100ft if not shown.

2. **Vertical (Riser):**

    * `Area` = "Typical - Building All Levels"

    Takeoff: `COMMON ASSEMBLIES`/`MISC ASSEMBLIES`/`TRASH CHUTE RISER CIRCUIT...`
    * Length = average floor to floor height
