This gives the panel designer flexibility: use the 35 A fuse where uptime matters, or the 100 A where fault-clearing capacity is the priority. ## Termination & Wiring Main circuit terminals are screw-type, accepting 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or max 2x (0.75...4 mm²) solid/stranded, with AWG equivalents 2x (16...12), 2x (14...10), or 1x 8.
