Electronics guy not electrician we use fuses that start out the size of your thumb to as big as you leg.. We mostly do not do electronics lol
people always assume we also know electronics.. 26 yrs electrician but electronics, its all new to me.. When we solder its called sweating and it's with a torch and rod, a lug sometimes as big as your fist..
Ratings work so different on electronics. We count sources add em up to common isolate between 15 to 20 amps or a very rare 30 amp. lol In commercial we start common @ 20 amps and 60 amps is highest used there except in machining factories..
