Im having some breaker issues in the shop when running the welder its tripping a lot and i have to keep running into the house. so the way I'm set up is there is a 15A breaker in the house for the garage, the wire runs into the garage and into a box with a "manual breaker?" you can push it to kill all power to the shop. so my question is can i pick up a 15A breaker and somehow wire it into the little box in the shop so it will trip that before the one in the house? it would save me a lot of foot work and tripping when the lights go out.

The thing in the shop sounds like a disconnect, just a big switch. I think the breaker in the house will still trip first, even if you added one to the end of the circuit in the shop. Also sounds very not to code.  What you really need to do is increase the amps to the shop. Maybe a 60A service run out to the shop from house panel, and a small panel in the shop with a couple of 15A circuits for lights and plugs,and a 20A welding circuit. you probably already know that, or your house panel is too small, etc. Lights and a drill battery charger and a couple of other little things, and the single 15A circuit is pretty much maxed out before you even start welding. The smallest welders will trip 15A breakers. You could* sneak a 20A breaker into the house panel. * not responsible for fires from overheated, under-rated wire. I will admit to having a dedicated 15A circuit with a 20A breaker for my 120V,135A welder. It never trips. |

Only way that would work is if you put a 20 amp in the house.
fyi welders draw up to 200%of their rated load.
because it is not continues draw it can be fuesed @ 200% its rateing while the wire can be derated to the listed load.
seperate section of tge canadian electrical code.

even IF you put a 20amp in the house, depending on how long the wires run to get to the welder, you may still pop the breaker, as the longer the run of wire, the higher the resistance.

don't put a 20A breaker on the house if its only 14ga wire in spite of what others are saying.... but if you do, then enjoy your pile of ashes

not something I'd recommend. my post was a hypothetical thought.
I can't say much though, have 14/2 wire in the barn and used to blow 20amp fuses, switched to 30amp fuses. No more fuses burning out. All wire is exposed and have checked it to see it it was making heat. No signs.

Now theres a fire waitn to happen. like most enginereered equipment the tolerance for wire is way over rated,but I would not fuse a 15 amp wire @30amps for a continous load. 2 suggestions:A)replace the feed wire with a 10 gage feeder. B) double your fire insurance ooo and change that fuse to a 15 before the fire department and your insurance apraiser gets there. this is the reason insurance companies want fuse panels removed.

Barn is due for a re-wire once the floor is poured. will have all 20-amp circuits, and designated outlets for the welder.
