![]() Maybe could try looking for a slightly higher amps? Maybe 35 /trip ~42? Others EE types here have used fuses, of a special type. I don't know alot about sizing breakers to protect windings.but your "it says fl amps 30, trip 37.5 " sounds ok. But that matches the way windings heatup. High amps overload trips fast, small overload takes longer to trip. SD style protects house wiring, and by design allows long term (1-2hours) small overloads, that just the way code works.Įven on this style breaker tripping depends on intensity of overload and duration of overload. I believe this style breaker does that better than the Square D style. For protecting windings, it's better to select a lower amp rated breaker than a higher one. what you really want this style breaker for is to try to protect the gen's windings from thermal temp rise. So current will more or less divide up between the 2 wires, so wires /spades don't get too hot.Ībout breakers. So I meant run 2 wires from breaker (input/line) screw terminal, and plug each wire into a separate spade blade at the gen's big black terminal block. I assume a breaker rated for ~42A will have screw terminals instead of spade. I don't know what spades are rated for in amps. As you start to get up there in amps (42A) I start to get concerned that you may be going over the current rating for the spade connectors. Yeah if i look for info on that breaker number i think i have, it says fl amps 30, trip 37.5 so thats probably what i have. ![]() the output wires were getting warm, not hot by any means but i could feel a slight temp increase in them. i'd still really like to toss a new 40 amp or close breaker in there though, or better. but then with the 4500 watt draw i tried an angle grinder and then a few seconds after it would trip the breaker. I tried to load test it yesterday, ran 2 1500watt heaters, then added a heat gun on high, 1500 also and tried another 1500 watt heater and it was ok but that heater didn't put out much, no better when i plugged into wall and no rating so i would disregard that. and im not 100% sure what you mean parallel a pair of wires from the spade connectors? like run an additional one from where it gets power and then run a 2nd one to the plug i'll have, from the breaker? ![]() ONAN Part number 0167-0272: SPARK PLUG This item is part of the superseding sequence 167-0272 > 0167-0272 wt=.Yeah i should definitely see if i can find a 40 amp or something from there.
