How do the Zinsco 'red-tab-stab' CBs work/release wire??
Back in the 1960s, when men were men--and MILKmen apparently were total studs--ZINSCO was in a race to the bottom of circuit breaker quality. They actually put serious and deliberate thought into how to make their products lead the way in fire and shock hazard. Verily, the real world results show they succeeded. ;')
Anyway, Zinsco actually made CBs--up to 20A--withOUT screw-downs for the load wires! Yeah, basically "backstabs", but with this red tab protruding above the wire hole. The red tab is flimsy, but if you push it in just the right way, you feel/hear a definite click... but it still doesn't loosen its grip on that bare copper...
... SO, what's the Jedi trick to disconnecting this dreaded sub-genre of the larger and greatly dreaded ZINSCO family of not-so-fine ee-lek-trikal products?
Thanks in advance.
