Thank god someone finally explained that. Great explanation and the visuals helped. Almost impossible to find this explanation anywhere. I have a Siemens main panel with QP breakers and I'm planning to add a sub panel this week.This explanation filled in the gaps for me. Very much appreciated.
You are how an electrician should be, sir. Tip of the hat to ya. Just recently realized my electrician loaded up my Siemens panel with Eaton breakers and none are the CL type. So frustrating that they seemingly works but they don't belong in my panel. I didn't know the difference between type C and typle CL so I didn't say anything at the time. The funny thing is, this seems to be super common in retrofit jobs. They just buy bulk of whatever is cheaper and they install it in everything. Now i don't know if the difference between C and CL (Classified) is the listing/testing only or if they are any different. But it is not correct regardless. So frustrating. I guess i should replace all of them at some point and perhaps get AFCI breakers while at it as the new code requires AFCIs on pretty much all circuits.
And here I’ve been scouring the web high and low trying to find a tandem QP. My panel is full and I need to make room for a 50amp for my portable generator.
@@AGEElectricInc I was able to use a triplex in my box. 40amp double pull with 20 on each side. Freed up 2 spots for my 50amp generator install. Glad I found your channel.
I have a Siemens Main Panel that has QT breakers installed. Can I install a 100 Amp Double-Pole Type QP Circuit Breaker onto this panel? I'm installing a Sub Panel and looking for a 100A breaker that I can install into my Mail Panel to feed the Sub.
Yes, type QP breakers will fit anywhere in the panels. It's the QT breakers that have the rejection tabs and are limited to certain locations on the bussing. Like the example of a Siemens 30/40 panel where QT's can only be located in the bottom 10 spaces. I typically like to mount the higher ampacity breakers closest to the main if possible, or if I am going to relocate existing circuits into the sub-panel. A lot of times I find it isn't much more of a cost to just upgrade the existing panel to one with more spaces but there are a lot of ways to accomplish the same task and a lot of unknown variables on my part. Best of luck and be safe!
Good catch! Yes, we informed the owner of the compliance issue with those breakers. They chose to not correct it at that time. Although, we were able to get rid of a Square D 2-pole 50a that was in there and got consolidated with the QT breaker. It seems almost every home I go to I'm following people that don't understand that just because it fits doesn't mean it should. Though Eaton does have a line of "UL classified" breakers that are listed for use in multiple manufacturers. They do come with a higher price tag but they can keep inventory down.
A QT breaker is a tandem , triplex, or a quad breaker. So in a sense yes, they are the skinny style that allow you 2 spaces in 1. They will only fit or mount to the bussing in specific spots in a panel. For instance if you have a 30/40 space panel, that means there are 30 full 1' spaces available. To get an additional 10 spaces to make it a 40 space panel only the bussing on the bottom 5 spaces on both sides have a notch that will allow type QT breakers to fit there. Panels typically have this information/diagrams on stickers on the inside of the covers. Hope this helps.
Thanks for video, nice headlamp! My panel is a EQ8695 w busbar accepting QTs anywhere and no double lines on diagram like yours. HOWEVER, QTs aren't listed under any of the branch breaker listings. It's no where close to being overloaded and it's well balanced but I do have 6 QT tandems running lights inside and out of a

Appreciate this video my guy!
During my 50 years as a sparky I never used a twin circuit breaker higher then 20 amps. They run hotter and with heavy loads they don't last too long.
And here I’ve been scouring the web high and low trying to find a tandem QP. My panel is full and I need to make room for a 50amp for my portable generator.
Glad this could help!

Eaton breakers in a Siemens panel?

So QT is twin and QP is single pole? Is that what you're saying? It's hard to find this info. Thanks.

Cool video. Thank you
