California C-20 exam practice question · Fabrication, Installation & Startup

Landscaping blocks normal access to an outdoor unit disconnect. What electrical correction is required?

  • Provide the required rated and readily accessible disconnect
  • BUse the thermostat as the disconnect
  • CLabel a remote breaker only
  • DRemove grounding for access

Why A is correct

The best answer is: Provide the required rated and readily accessible disconnect. Service personnel need a readily accessible local means to isolate equipment as required. A control command is not normally an equipment disconnect. The transferred operating condition requires the same design, installation, diagnostic, or safety principle in a different HVAC context. The other choices skip a prerequisite, conflict with the listed procedure, or treat a symptom without controlling its cause.
