Dryers and AC units

Im installing AC for the new up stairs but I don't have any more 220 slots in my braker box for the unit, can I link it up with the dryer or range?

No you may not link up an air conditioner receptacle on the stove circuit or something like that.

Putting in a 240 volt (double pole double wide) breaker usualy needs just two consecutive breaker slots although not all possible paired positions might work. Usually you can move other breakers around in the panel to free up a pair of positions that do work, namely on opposite sides of the 120/240 volt service to give you the 240 volts.

You can install a subpanel to give yourself more breaker slots. If more convenient you c an move existing 120 volt circuits to the subpanel and put the new 240 volt breakers in the main panel.

Most cities require a permit for a subpanel and some require a permit for new circuits of any kind.

It is possible you will need to do a load analysis (procedure is in the National Electric Code book) and in some cases you may need to put in a new service (fatter wires coming from the utility pole and meter) and a new main panel.

Many cioties require a separate permit for a new service and.or new main panel.


The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.

Alan what you can do is change some of your single pole breakers to space savers. At the bottom of your panel (in the last 4 spaces for breakers) It should accept the space saving beakers that are only half the width of the regualar single poles. You can take 4 single poles and only take up 2 spaces leaving room for you to get your double pole breaker in. Also, you might get the idea to try a space saving double pole. It will not work because you have to have current from 2 different sides of the panel to get 240 so you have to click in to full spaces. Its hard to explain with out showing you and empty panel. Anyways just go with the first way and it will work. A picture world be great though as cowboy suggested. Because a panel in your part of the country maybe different than what we have around where I am

Not all panels accept half size breakers. Your panel label should tell you what kind of breakers it will accept. Post a pic of the panel with make and model number.
