	Subject - breaker panel jiraffy CAN I MOVE BREAKER POSITIONS [FOR EXAMPLE;GOING DOWN THE RIGHT SIDE OF THE PANEL IT GOES 15 20 15 20 CAN I INSTALL TWO TANDEMS 15 15 20 20 IN PLACE OF THE SINGLES]AND RELABEL ON THE DOOR WHAT CHANGES I MADE .THIS TO INSTALL A DBL. POLE 60 FOR A NEW SUB PANEL.THANK YOU. kbsparky Tandem breakers are used to "cheat" when you don't have enough space left in the panel for the number of circuits you want to connect. If your panel is not already loaded to the max (42 circuits total, counting double pole breakers as two) and the panel is rated for use with tandem breakers (some are not), then the installation of tandem breakers may sometimes be utilized to offer more circuit connections. See NEC 408.35 Another issue is rearranging circuits in an existing panel to accomodate tandems. If multi-wire circuits have been installed, it is imperative that the phasing of those circuits be maintained, that is each leg of the multi-wire circuit must be connected to the opposite phase of the panel. Otherwise, the neutral conductor of that circuit can be seriously overloaded. Also, it should be noted that some jurisdictions prohibit the installation and use of tandems. What does your local inspection authority have to say on the subject jiraffy i can use tandem breakers and all the breakers are single phase [meaning only one wire per breaker] jiraffy to my last reply ,i think only one wire per breaker means single phase,and my panel is 200amp service with nothing overloaded. i Energreen Where's the sub panel going to be installed? Is there any possibility of moving two single pole circuits to the new sub to make room for the sub feed? EG
