Following are some guidelines for electrical wiring in greenhouses that are being constructed to grow tobacco transplants. A greenhouse is distinctly different from a residence; different wiring practices should be used. This material closely follows the National Electrical Code (NEC) but is not intended to be a complete installation guide. The purpose is to provide some basic suggestions for planning a safe electrical system. Additional details can be found in the "Farm Buildings Wiring Handbook" (MWPS-28) available from the UK Ag. Engineering Plan Service.
