# Electrical Takeoff

> [!important]
> Complete [[pre-takeoff-research]],

> Use [[heating-designations]] for uncertain scope.

## Lighting Control

By PDI convention, [[lighting-controls-takeoff]] are generally "Electrical", not "Lighting".

## Receptacles

## Floor Boxes

### Poke-Thru's

## Homeruns

### Lighting

Takeoff homeruns in Building breakdowns,
even serving Amenity spaces.

> [!info] Breakdowns
> * `Area` = "... Building"
> * `System` = "Building - BOH ..."

## 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.

.../`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

### Trash Chute

**Horizontal:**
* Check if shown on power drawings as mech connection
  * If not, use 100ft length

**Vertical (Riser):**
* Takeoff: `COMMON ASSEMBLIES`/`MISC ASSEMBLIES`/`TRASH CHUTE RISER CIRCUIT...`
* Uncheck Link 'Enable Livecount'
* Takeoff in Typical
  * Length = average floor to floor height
