Show answer and rationale
Correct: D. Section 82.157(c)(2) sets three thresholds: twenty percent for commercial refrigeration, thirty percent for industrial process refrigeration, and ten percent for comfort cooling and everything else. All are gated on a fifty-pound full charge.
- A — Thirty percent is the industrial process refrigeration threshold, not the commercial one.
- B — Ten percent covers comfort cooling and other appliances not in the first two categories.
- C — Fifteen percent is not a threshold in the rule, and the charge gate is fifty pounds.
