What''s the max bend you can put on PV wire, module leads

Electrons don''t care about bends, but the wires care about heat - stress points increase the heat on the wire & insulation. Heat is the #1 reason why wires fail: annealing metal increases resistance -> more heat; heat damage to insulation introduces expansion/contraction which causes pitting; pitting allows water to enter the wire and cause faults.
