![]() ![]() should i be doubling them up too or is it just the hot i need to worry about reallyġ) I was just rereading this whole thread. So i'm not imagining things when it looks like they are coming from the same place? it looks as though there are a couple unused spade's coming off that line of connections below L1, L2 and 元. Neutral and ground wires.For each one, I think would do the following: In the control box (where the gen breakers are) I'ld run 2 short wires with spade on end to thermal power block. Im not quite sure where you mean when you say this: Yeah that price tag is rediculous but i'll do it if its what i need to do it right. I think $20-30 is more inline, but I haven't priced them. Just noticed that 35A breaker you listed is $88. It's a electrical code issue, although I think may people ignore it. Depending on how you are using a generator sometimes you have that bond in the generator (like for a standalone outdoor event, construction site, or RV use ), sometimes that N/G bond is in your house breaker panel. That's the neutral / ground bond connection. Even on my 7kw Marquis each spade is only carrying 30A max, I don't know what the spade's limit is, so I'm trying to be conservative. This doubling up is because I'm concerned that spades may heatup drawing 42 amps. With other end of them wire-nutted to a larger wire out to what ever I want to power. (maybe 8gauge, or could go 10gauge with high temp rating on insulation) (7kw at 120V = 58A, has 50 amp sticker on side of gen unit.ĭisclaimer: I have no experience matching up breaker protection to gen windings thermal rise.įor the wiring from the new breaker to whatever you power I would go with 1 wire that will carry ~42A. The parts list shows you have the same stator as in my Maraquis 7NHM, which has both 20 and 30 amp breakers. I think the breaker you reference (FL amps 35, trip amps 43.8) sounds OK to use. 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? Yeah i should definitely see if i can find a 40 amp or something from there.
