I need to add a 20A 220V circuit to a GE panel. The problem is that there is only one open slot in the panel. To add the 220 breaker I need to replace one of the breakers with a tandem breaker. The breakers I find at the home centers do not have a deep enough slot where the breaker connects to the buss. What type should I be looking for? -- Don Bowen --AD0NB--
