What is everyone using to calculate their bus bar current rating? I've always heard that 1.6 X mm2 of the bus bar, but I've been reading that that might be too generous. Some say 1.5 others say only 1.2. Curious what everyone does. For example 1/4in x 3/4in thick which is 6.35mmx19.05mm = 120.9675mm2
If that's 1.6 x 121mm2 = 193.5 amp rating
1.2 x 121mm2 = 145 amp rating
That's a pretty big difference. But interestingly enough, that's about the same size as 4/0 wire? I feel like I'm off here as 4/0 is supposed to be able to carry a lot more than 200 amps.
