EasIER, yes. but more than the suggested pin size of, what is it, 0.025"?

Without doing "The Twist", you're forcing the breadboard to take the full width of the TO-220 pins. Looking at my ON Semiconductor data sheet for a TIP122 power transistor (to pick one example), that width is spec'd at 0.025" to 0.035". I checked a couple of units and got 0.032" for both.

But by giving each lead that 90 degree twist, the breadboard now only has to accommodate the thickness of the lead, which according to the data sheet is 0.018" to 0.025". On the units I checked, it was 0.021".

Like I said: TO-220 devices are a lot easier to insert into breadboards if you give their leads a 90 degree twist. Works every time, I've been doing it for years.

Tried it. dang, it sure does.

Just for the record, I finally found technical info for breadboards, I assume all are equal. 36 V max, and 2 Amps (I assume that's total).
