Introduction: Rabbit-proof Extension Cord
We have some pet rabbits that are partial to electric insulation. They have nibbled through audio and video cables, and chewed the insulation on power cables.
To preserver a laptop power cord, and for that matter to stop the rabbits being electrocuted, I made a rabbit-proof extension cord.
In Canada flexible armoured conduit is required for wiring up lights etc. in an air plenum, so it is readily available.
It is only single-strand cable, but the covering keeps the bending radius large so it's not a serious issue. I fitted a regular 110V cord-end plug and socket, and clip the socket end to a tabletop so that the unprotected cord does not fall to the floor.
