They also make the electrical-wiring equivalent of a cable toner, which is something I've wondered about for ages. Having recently bought a house wired by an electrician who did fine work in the conduits but seems to have struggled with the command of written language required to produce legible labels in the panel, I expect to get good use out of the one I've just ordered.
