Explain the operation of a ground-fault circuit interrupter. Why are GFCI devices used? Where are GFCI receptacles required? _________________________________

Expert Solution & Answer

To determine

Explain the operation and need of a ground-fault circuit interrupter (GFCI) and also mention the area that requires GFCI.

Explanation of Solution

Discussion:

A device that senses an unbalance current flow is ground-fault circuit interrupter (GFCI). When a ground fault exists in a circuit, an unbalanced current occurs. This type of current flow may cause death or injury to a human being. The flow of unbalance current is stopped by GFCI. When the value of current exceeds 6 mA, the GFCI trips the circuit to OFF. The GFCI protection is supplied by a branch circuit breaker, GFCI receptacle or by a dual function AFCI/GFCI.

According to an article NEC 210.8, a 125 volt single-phase 15 and 20 amperes branch circuits require a GFCI protection at specific location such as kitchens, bathrooms, outdoors, garages, and within 6 ft(1.8 m) of the top inside edge of the bowl of sink, swimming pools, and hot tubs.

Conclusion:

Thus, the operation, need and the area that require GFCI are explained.

Pastner Brands is a calendar-year firm with operations in several countries. As part of its executive compensation plan, at January 1, 2024, the company issued 480,000 executive stock options permitting executives to buy 480,000 shares of Pastner stock for $38 per share. One-fourth of the options vest in each of the next four years beginning at December 31, 2024 (graded vesting). Pastner elects to separate the total award into four groups (or tranches) according to the year in which they vest and measures the compensation cost for each vesting date as a separate award. The fair value of each tranche is estimated at January 1, 2024, as follows: Vesting Date Amount Fair Value Vesting per Option: December 31, 2024 25% $ 3.90 December 31, 2025 25% $ 4.40 25% $ 4.90 25% $ 5.40 December 31, 2026 December 31, 2027 Required: 1. Determine the compensation expense related to the options to be recorded each year 2024-2027, assuming Pastner allocates the compensation cost for each of the four…
