You probably won't want to build a meter that will be accurate enough with an inductive load like a refrigerator. But I've seen surplus real electric meters (like the one on the side of the house) for about $15-$20. You might try Herbach & Rademan (now H & R Corp.) at 401 E. Erie Ave, Philadelphia PA 19134, 215-426-1708. One of their older catalogs has one... they might still have some around. Good luck! Dick Wotiz dick@portal.com {sun|uunet}!portal!dick
