HVAC disconnect checklist playbook

Goal

Provide a compliant HVAC disconnect that is properly located and rated.

Inputs you must know before you start

  • Equipment nameplate and instructions.
  • Unit location and working space constraints.
  • Circuit rating and disconnect type needed.

The path (in order)

  1. Confirm disconnect requirements in equipment instructions.
  2. Select a disconnect with correct rating and type.
  3. Place the disconnect within sight or apply allowed alternatives.
  4. Verify working space and access.
  5. Label and test disconnect operation.

This is

A quick checklist for HVAC disconnect placement and sizing.

This is not

A guide to motor circuit sizing or HVAC equipment selection.

Inspection-ready checklist

  • Disconnect rating matches equipment requirements.
  • Disconnect located within sight when required.
  • Working space is clear and accessible.
  • Disconnect labeled and tested.

Worked example

A condensing unit requires a fused disconnect. You install a rated fused disconnect within sight of the unit with clear working space and label it with the circuit source.
