Bootleg ground

In building wiring, a bootleg ground is an electrical ground that is wired from the neutral side of a receptacle or light fixture in an older 2-wire home. 〔Steven Bliss ''Troubleshooting Guide to Residential Construction ''Craftsman Book Company, 1997 ISBN 1-928580-23-8, page 287〕 This essentially connects the neutral side of the receptacle to the casing of an appliance or lamp. It can be a hazard because the neutral wire is a current-carrying conductor. In addition, a fault condition to a bootleg ground will not trip a GFCI breaker or a receptacle that is wired from the load side of a GFCI receptacle. Bootleg grounding is illegal and against code in many places. A safer and legal alternative to bootleg grounding (where a local electrical code allows it) is to install a GFCI and leave the ground screw unconnected, then place a label that says "No Equipment Ground" on the GFCI and all downstream receptacles.
==240 volt circuits==
Before 1996, in the United States it was common to ground 240 volt appliances (such as a clothes dryer or oven) to neutral. This has been prohibited in new installations since the 1996 National Electrical Code.
