Yep. Safety first. FYI I did install this (see picture below)and 30 AMP breaker dedicated to the generator last night. I had them laying around so I went ahead and did it. I still need to get a female 30a plug to replace the male "suicide" plug as you call it for the 30a genset cable. So you did have a little effect.
There you go, now how about that interlock kit, lol.
