Hawaii Residential Appliance Installer License Prep Class Installation: Essential Questions and Calculations

Aspiring residential appliance installers in Hawaii must prepare for the PSI state licensing exam to demonstrate their knowledge and skills in electrical installations. The Hawaii residential appliance installer license prep class installation course offered by Texas Journeyman Electrician is designed to simulate actual exam conditions, providing students with a comprehensive study program that covers essential questions and calculations.

One of the critical aspects of electrical installations is calculating the correct size of electrical boxes and conductors. For instance, when four 2″ conduits enter and exit an enclosure, what would be the minimum size electrical box required? To answer this question, one must consider the external installation voltage (600 V) and apply relevant NEC codes.

Another important calculation involves determining the maximum conductor ampacity permitted for a given installation. In this case, ten conductors (12 AWG, THHN) are used at 86°F (90°C), and the correction factor from Table 310.15(B)(1)(1) is applied to determine the correct ampacity.

A further calculation involves determining the calculated minimum size feeder circuit conductors for multiple motors on the same feeder. For example, if two motors (10 HP and 2 HP) are connected in a three-phase, 230-volt system, what would be the required conductor size?

The Hawaii residential appliance installer license prep class installation course addresses these critical calculations and more, providing students with real-world exam scenarios, code references, and detailed explanations. With a comprehensive Home Study Computer Program, tutoring, and live seminars, aspiring installers can confidently prepare for their PSI state licensing exam.
