More old homes are being purchased and re-modeled than ever. It is estimated that there are 22 to 23 million residences whose wiring differs in major way from today's accepted standards. This book helps electrical professionals deal with virtually any difficult electrical problem encountered in old houses and apartment buildings--including historic residences--in addition to smaller commercial structures. Filled with helpful drawings and illustrations drawn from old electrical reference books, it should become the major how-to reference on old electric wiring for electricians, contractors, inspectors, and other professionals. It also will be a valuable resource to sophisticated do-it-yourselfers who have purchased an old home and are doing their own renovating.
