Combining Circuits
Hello,
We are trying to install a 240 dryer outlet to our existing panel however all slots are being used. I'm curious if I calculate the possible load for a circuit if I could combine it with another in effect freeing another slot.. The way the panel is broken down is as follow. Two pole 40a, Two pole 30a, Two pole 30a, 6 - 20a slots, and 4 - 15a slots. Panel is 125a I believe. All are in use. How could I rework to free space for addtional two pole 30a. Without getting another panel or having to install a sub panel. There must be a way. Help is greatly appreciated.
Thank you

In theory, you could combine two circuits into one if the load allows it, and if neither circuit serves a kitchen, bathroom, laundry area, or dining room. However, I doubt that this is the best solution. Other possibilities include:
- Using tandem breakers. If you tell us the model number of your panel, we can tell if it is designed to accept them.
- Installing a subpanel next to the main panel.
- Installing a larger main panel. This probably isn't the cheapest idea unless you are also upgrading the service size.

I'm not an electrician so I'll let the experts weigh in as to whether there might be code issues, but ...
I have seen half width single pole breakers (1/2 inch wide instead of the normal 1 inch wide) at Home Depot here in Canada. There were Siemens for sure, maybe Square D also.
Since two half wide breakers take up 1 knockout on the panel face, you could replace the 4 15amp single pole breakers with 4 half width breakers then you will have 2 free spots for the double pole 30amp breaker for the dryer.
Might be worth looking ...

Here is a .pdf spec sheet for the Siemens breakers I mentioned.
I don't know if these work with your panel or if the panel mfr. has something similar.

Would the Zinsco Two-pole twin on this page work? It looks to be as wide as the Zinsco single pole. It can be ordered as 15/20 amp so each side seems to operate separately.

I have doubled up on circuits many times in older homes where some actually had nothing or only a couple lights on some of them. You should do some research and see where they go. Often bedrooms have little use. Some breakers are not meant to have 2 wires, in that case pigtail them. Here is a great site to do some research. http://www.homewiringandmore.com/index.html
