Wire Tips
◊ Use properly-adjusted wire strippers only (not
cutters or teeth). Stripping must not affect
the conductor in any way (scrapes, cuts or
nicks).
◊ The strip length should the height of the
breadboard minus approximately 2 mm.
◊ If wires are too short, there may be poor electrical
contact. Frustrating error as it appears connected.
◊ If the wires are too long there is risk of a short
circuit.
