An electrician needs to select a _____ ampere dual element (time-delay) fuse to protect a 30 hp, 208-volt, three-phase, squirrel cage, Design B motor that powers a warehouse conveyor belt.
The correct answer is

The FLC is 88 amperes. Step 2: Refer to Table 430.52(C)(1) for the maximum rating of a dual element (time-delay) fuse, which is 175% for a Design B motor. Step 3: Calculate the maximum fuse rating: 88 × 175% = 154 amperes. Step 4: Round to 175 A for the next standard size fuse

The hint refers to the sections and tables in the NEC codebooks that provide information on calculating the minimum size of a junction box based on the number and size of conductors. In this case, we have thirty-eight No. 10 AWG XHHW conductors joined in pairs. The referenced sections and tables will help determine the required volume of the junction box, which can then be used to select the appropriate box size from the given options.
