*Wire sizes: gauges specified are the minimum allowable as per CSA and UL standards.
The 9926 circuit breakers do not have provisions for marking tags. A possible solution is to cut the adhesive SchS2 tag rail to length (approximately 20 mm on a single pole unit so the current rating remains visible or approximately 30 mm on a two pole unit).The SchS2 accepts DEK, WS and ESG 8/17 marking tags.The part number for adhesive SchS2 is 1720600000.
Additional trip curves and amp ratings are available upon request.
