## In plain English

### What the equipment does

Switchgear groups the devices that connect, disconnect and protect power circuits. A switchboard takes an incoming supply and distributes it to outgoing circuits.

### A simple example

Use OT125GDUU3BZ_STEP.STP.stp (revision A) to place the original solid geometry in your 3D assembly.

### What the drawings help you do

Use OT125GDUU3BZ_STEP.STP.stp (revision A) to place the original solid geometry in your 3D assembly.
