To get the most up-to-date wiring changes for a building or expansion project, check out the recently revised "Agricultural Wiring Handbook" which is available from the National Food and Energy Council (NFEC). The 100-page handbook describes changes made in the National Electrical Code, a document that establishes requirements for all electrical installations.

The handbook also includes simple wiring plans, stand-by generator options and wiring considerations for farm buildings. It is available for $10.45, plus shipping.

To order, call NFEC at (573) 875-7155.
