Attached is image of my panel image of electrical panel in my garage. In the past I explored a possibility of adding a subpanel as I have few wood working machines and running the dust collect and planer trip the 15 amp circuit in the garage. I got great help from this forum but I never got to add the panel as the only thing I need is another outlet (120 or 240 either would be ok) on a different circuit.

So I am now considering 2 options -

  1. Replace the 220v dryer breaker with a quad 20/30 breaker. This will help me give a 20 amp 220v breaker. The problem is I don’t find EATON quad breaker 20/30 combo in local stores anymore. I did find on eBay but there are 2 models - BRDC220230 and BQC220230. I am wondering what’s the difference between them and what other manufacturer circuit breaker can be used in my EATON panel. My panel seems like have BR style breaker (I don’t know what it means). The existing quad breakers are BQC series.
  2. Another option I have is to splice an outlet (120v) from my media outlet dedicated circuit. I took this for my audio equipments but for now I only have 1 receiver and they never will be used align with wood working tool. This would mean I will need to ping tail the original wire and attached to the same breaker. I am assuming the outlet needs to be GFCI as it would be in garage. Is there any concern here?

Among these 2 options, wondering if there is any advantage/disadvantage if one over other assuming they both serve my purpose.

Thanks in advance. enter image description here

  • Can you post a photo of the label on the inside of your electrical panel's door please? Jan 16 at 17:12

Your panel is Circuit Total Limiting, apparently, so you'll want a BQC220230

From the labeling on your panel having references to rejection-type bus stabs, we can tell that your panel is what's known as a Circuit Total Limiting (CTL) electrical panel. These were developed in the 70s to enforce the old NEC prohibition on having more than 42 circuits coming out of a single panel. However, since that restriction was lifted in the 2008 NEC, the current Eaton panels have dropped the CTL feature, as they are listed and labeled to be double-stuffed to the gills.

The good news is that while they're no longer needed for new panels, Eaton still makes CTL tandem and quadruplex breakers in order to support existing BR CTL panels. You'll want a BQC220230 for your situation; this provides a 2-pole 30A common trip breaker on the inner poles for your dryer circuit, while providing a common-trip on the outer two 20A poles as well. This latter feature not only lets you run a 12/3 out to the garage for your new tools circuit, but also permits you to put 240V receptacles (NEMA 6-20R) on the circuit in addition to the 120V receptacles, with the small caveat that under NEC 2020, you'll need a "spa box" GFCI at the garage to provide GFCI protection for the mixed circuit.

  • Thanks ThreePhaseEel. I was able to add a new 20 amp 240 v circuit using the information you provided. Thanks a lot. I have one additional question, I ran a 12/3 wire with the Hope that I can have both 240V and also 120v receptacles. For 120V receptacle, are there any restrictions that I should be aware of ?I do have neutral so that’s not a problem, I am assuming as this is in garage, it has to be GFCI outlet. Can this be in the same box or it has to be in separate outlet box?

  • @Ashterisk -- if you want to GFCI protect the circuit, you'll want a "spa panel" (it's a small breaker panel with a 40A or 50A GFCI pre-fitted in it) that goes inline with the circuit before the first outlet -- your other option would be to use individual 120V GFCI receptacles, but you can't get 240V versions of those Feb 1 at 0:58
  • thanks for the response. Sorry I meant for the 120V outlet that I will want to add to this circuit, I believe it needs to be GFCI outlet. Is that correct? I only plan to put one outlet so thinking will just use the GFCI outlet ONLY if needed.

  • @Ashterisk -- you can put a pair of 120V GFCIs in for now (you'll need a pair since you can't use a GFCI as a split receptacle) Feb 1 at 2:38
