Look through your breaker box for the circuit breaker which stands out from the others. If a circuit breaker is damaged, it will likely have tripped, cutting power to the section of the home it controls. You should only replace a circuit breaker that has broken or been damaged in some way. Not a trivial task, but if you provide more specifics about what you have currently have and what you are able to do in terms of changes to the wiring, we can provide more help.Locate the defective breaker. Even better, if you bring in 30A 240V (hot/hot/neutral/ground) then you actually get 60A of available power at 120V, which should be more than enough based on your question.Įither of these solutions is dependent on being able to run the correct wire (i.e., 10 AWG but the correct # of wires) from the main panel to the shed, and proper installation, including grounding (you may need ground rods as well as connecting the ground wires correctly). If you bring in 30A to a subpanel then the subpanel can have multiple 15A or 20A circuits connecting to individual breakers in the subpanel. It can be tricky to install properly, but in limited circumstances can be a solution. Actually it isn't two-for-one, more like two-for-one-and-a-half, because (ignoring ground) you use 3 conductors to get twice as much current as 2 conductors. Using 20A and 12 AWG wire connected to a pair of breakers, you can wire things up so you have 2 circuits instead of one. This is a neat "trick" where you have 2 15A or 20A circuits sharing a neutral. There are a number of possible solutions. However, you have an expectation here of needing on the order of 30A total current, presumably at 120V. Code is generally written so that anyone encountering a particular item (e.g., a 20A receptacle) will be able to expect specific safety rules to be followed. the next owner (or even just a visitor) may not realize the limitations and try to plug in too much stuff at one time and end up with a fire. In case you are wondering, in addition to the "device" problem, there is also the idea that while you know exactly what is going on and what can be plugged in where, etc. But generally speaking that is the main exception and you can't mix 20A and 30A. Similarly, a typical device designed for a 15A circuit can be plugged into a 20A receptacle. Note that this "always match" rule does have some exceptions regarding 15A & 20A - a 20A circuit (breaker with 12 AWG wire) can have 15A and/or 20A receptacles. A device designed for a 15A circuit could have a malfunction that caused it to pull 25A of current expecting that a breaker trip would stop it before it caught fire, but on a 30A breaker that doesn't happen. are rated based on the amount of power they normally use and what they can handle when things go wrong. You can't use a 15A or 20A receptacle on a 30A breaker because if you had an overloaded device (not planned - malfunctioning) that pulled 30A, it would melt the receptacle but the breaker wouldn't trip to stop it. Wiring - A 30A breaker can have 10 or larger.
