A sign circuit is expected to operate for long periods during business hours. What is the best load-planning principle for the contractor to raise during review?
Correct Answer
B) Confirm the design has margin for continuous operation
Confirm the operating duration and load classification with the electrical designer, then verify conductor, protective-device and assembly ratings. Continuous-duty capacity depends on the approved equipment and installation conditions, including whether a suitably listed 100%-rated assembly is used. Neither instantaneous current alone nor an arbitrary doubling establishes the design. Source: https://www.se.com/us/en/faqs/FA104355/
