Tandem Breakers for I-T-E Imperial Circuit Panel
Panel Board: AV719711
Catalog NO: EQ20MBB
120/240 volts AC1 Phase
3 wire 200 Amps
20 slots
This is a 45 year old circuit panel. I would like to add an extra dryer(3 wire) to my circuit panel, and the circuit panel is full. Can I add a tandem breaker to my panel? Are tandem breakers allowed for this old circuit panel? If not, what would be the best route to go to add this extra dryer to an already full circuit panel?
Thank you

Best solution short of replacing the panel is to add a subpanel.

old thread, but in case someone else is searching like me ... the label in the EQ 20MBB panel shows that tandems can be used in all of the breaker positions, with an additional caveat that "the sum of the EQ-T breaker ratings not to exceed 110A per branch circuit bus stab"
for completeness, the top row of breakers uses the left stab, the next row down the right stab, etc.
since my panel is all 20A or greater breakers, I can have four 20A tandems as long as I put two on each stab. If I want to drop a couple existing circuits down to 15A, then I can additionally replace two 20A singles with 15A tandems for a total of six tandems in the panel.
apparently the convention of sticking the tandem capacity info in the part number wasn't around/used by ITE when the panel was made.

I think that you are a bit confused on the bus stab limitation. It is not for the entire panel but for each row. The bus goes from top to bottom and at each full space is a stab. So your 20 space panel has 10 stabs. The idea of limit to 110 amps per stab is that you can't put a tandem 20 across from anything more than a 70 amp. A tandem 15 can go opposite a max of 80.
