## Content

### Terminations

When building
* [[#Panelboards]]
* [[#Switchboards]]
add **branch terminations** according to an example from the schedules.
**Do not include feeder terminations.**

## By Equipment Type

> [!tip] When in Doubt
> If the equipment is not listed below,
> use a distribution panel of equal amps.

### CT Cabinets

???

### SPD's/TVSS's

> Name = "SPD"

Labor only.

Specific item is not important, but I use
`SPLITTERS / SOCKETS / CABINETS`/`METER SOCKETS & CABINETS`/`METERING CURRENT TRANSFORMER`
(Labor = 1.5hrs)
for consistency.

### Submeters/Power Monitors

> Name = "Power Monitor"

See [[switchgear-takeoff#SPD's/TVSS's]]

### Switchboards

> Name = "Switchboard - 2000A, 4-Section"

### Panelboards

> Name = "Panelboard - 600A, 2-Section"

`DISTRIBUTION`/`DIST PANELS & UNIT LOAD CENTERS`/...

### Disconnects and Enclosed Circuit Breakers

`COMMON ASSEMBLIES`/`DISTRIBUTION`/`MANUAL DISCONNECTS`/...

### Generators

> Name = "Generator - 250kW, Diesel"

Add `DISTRIBUTION FITTINGS`/`GENERATOR SET UP`.

### Generator Connection Cabinets

> Name = "GCC - 200A"

Use a Distribution Panel of equal amps.
Or a transfer switch.

### Transfer Switches

> Name = "Transfer Switch - 400A"

#### Transfer Switches 1200A+

Use 1200A and add an additional `TRANSFER SWITCH` item
to make up the remaining amps.

### Meter Centers

> Name = "Meter Center - 800A, 16-Can"

`SWITCHGEAR & METER CENTERS`/`METER CENTERS`/`... METERING SECTION`

Adjust Factor 1 for meter stacks, delete zeroed items.
