CSLB Class B General Contractor's License Practice Exam

For an electrical disconnect to be compliant during HVAC installations, it is essential that it is accessible. This requirement ensures that in the event of an emergency, maintenance, or service need, individuals can quickly and safely reach the disconnect to cut off power to the HVAC system. Accessibility is crucial for safety and operational efficiency.

Other factors, although important in certain contexts, do not universally apply to all installations. For instance, having a disconnect located outdoors may be beneficial for certain installations but is not a requirement in every scenario. Similarly, while having a locking mechanism can enhance safety, it is not mandated for all types of disconnects and may depend on specific installation circumstances or local codes. The distance from the appliance, such as being 10 feet away, is also not a standard compliance requirement inherent to every installation. It's the accessibility that stands out as a fundamental requirement across various codes and standards, ensuring that personnel can act promptly when necessary.
