LSA 46.3 alternator family envelope and generator-set interface coordination.

## In plain English

### What it does

A generator turns mechanical movement into electrical power. An engine-driven generating set combines the engine, alternator and supporting equipment.

### A simple example

In a microgrid, a generator can supply loads when solar output and available battery energy are insufficient.

### What the drawings help you do

Use the selected manufacturer's drawings to check the equipment's size, mounting points and cable connections. The layout helps you plan where it fits and how it can be reached for maintenance. An illustrative 3D preview does not establish product dimensions or required clearances.

### Terms

- Rating: A value stating the conditions for which equipment is specified.
- Schematic: A drawing showing function and connections rather than physical appearance.

## What it represents

Set the selected alternator mounting and bearing configuration before reserving service and removal space.
Use the linked manufacturer drawing or project mechanical files for dimensions and the exact selected revision. This original educational illustration is unitless and not to scale.

## How to read it

- Check engine, skid and terminal-box interfaces.
- The CAD family contains mechanical variants; an alternator model is not a complete generator set or an electrical rating selection.

## Information to show or reference

- Record frame, bearing and coupling selection.
- Check engine, skid and terminal-box interfaces.
- Reserve maintenance and complete-unit removal routes.

## Important distinction

The CAD family contains mechanical variants; an alternator model is not a complete generator set or an electrical rating selection.
