The errors in diagrams and wiring instructions could cause people to be shocked or create a fire hazard.

In announcing the voluntary recall, the U.S. Consumer Product Safety Commission said no incidents have been reported.

The 951,000 recalled books have nine different titles, including “Lowe's Complete Home Improvement and Repair” and “Sunset You Can Build- Wiring.”

They have been sold at bookstores and home improvement stores in Canada and the US for years - some more than three decades ago.

Health Canada said it is not acting immediately on the US’ recall but will take the matter under advisement.
