I know this is an old thread, but it never mentions the following option for ROMEX- stripping only the flimsy outer insulation and removing the loose paper on the ground wire. The other two wires have been a pain for me to strip- possibly because of arthritis, even when using a TNT Tooling wire stripper. Anyone else able to do calculations for removing just the easy stuff and leaving the tight insulation on the other two wires? (I don't have enough experience yet to trust my numbers, or I'd do it myself)
