Soundproofing and other questions for Northern Lights M643

[phorvati]

So I am at a point where my generator is working pretty good. After much of the engine side maintenance I am relieved to see that AC side of things is good. I was able to confirm 117.5V AC RMS and was able to run small loads without stalling or any other issues.

I will get the brush set and fuses in anticipation of potential issues during steady use now that i have it running. I am not spending 900$ on AVR. those look to be potted in epoxy and should be good.



My main thing is how to build soundproofing. Did anyone make their own? looks like the dealer's part for sound proofing for M643 is not available. 39-78303
M673 has same dimensions and it appears that part might be available although dealer lists it as "Call for price"

While i would love to bypass the DIY on this, i think it might be best option.



I am not impressed with how small the output terminal block is. It does not make it feasible to crimp 8 AWG wire onto that terminal. Also, those wires inside the electrical box are 14 AWG. And they are supposed to carry 50A?

UL says as long they are inside a UL approved junction box they can be any size. Once you get out of UL approved box, you must follow amperage sizes.
