Electrical wires are often found on the crawlspace floor during a home inspection. Sometimes they are abandoned wires from a remodeling project and sometimes they are spare wires left by the original electrician in case other outlets or appliances are needed at a later date. The mentioned wire was found “live” or “hot” which create an unsafe condition for anyone accessing the crawlspace. The wire end should terminate inside of an approved electrical junction box and corrected by a qualified professional.
