We have ruined two electric blankets using a MSW inverter. At that time, we didn't know it was a problem. We have since switched to a pure syne wave inverter. No more issues!
Where is the twist lock in that ? The product just looks like it plugs into a NEMA 10-50R (3 wire range) and converts it to a 14-50R (4 wire range/RV/Tesla). The 10-50R uses the same conductor for neutral and ground which was allowed (with certain conditions) for many years, (not like a 6-50R welder outlet which has no neutral) Mike, have you verified that the ground is actually floating or is it possible that the ground and neutral on the 14-50 side are tied together? If so, it would be not much different than wiring a 14-50R to your main service. Not saying the adapter is a good idea, but I am really curious if they really floated the ground as one reviewer claims.
I’ve triple-checked, and the ground contact in the 14-50R (female) outlet is indeed isolated from all other contacts on both sides of the adapter. I’ll demonstrate this on-camera in our webcast next week. Pretty scary, isn’t it? 😱
Yes, that is just plain stupid. BTW Mike, when I include technical info in my comments it is because I know a lot of DIYs and others are reading, it is not intended for you as I realize you already know the info and probably more.
When I had a previous camper it had a quality MSW inverter. The only thing I ever plugged into it that would not work was an electric mattress pad. It did not over heat , it just did not work.

Yup, not a twist-lock connector!
🤣🤣🤣

That’s the correct way to add a comment. This is really a teaching newsletter, so more basic information is always better.
