You may want to re-read the thread. It’s not that you can’t plug a vac in. You can’t plug a vac AND a Dewalt in. The combined current when running both is too much. I run my vac off of 1 IOT relay and my Dewalt off another.
It’s not running two in his scenario. It’s running one at a time, which is perfectly within the current capacity of the relay. In a Normally On (Closed) and Normally Off (Open) scenario, there’s no way in a non-fault state that they are on at the same time. Especially on a mechanical relay that is physically breaking a connection and making a new one.
As for the Xcontroller, it’s current draw at A/C is max like 4A. So you could run an Xcontroller and a vac/Dewalt on a single IOT relay (the new version with an idiot proof “Always On” outlet) with no issues.
That’s not offensive. He didn’t personally attack you or anything. He just said that you had people try to help and YOU laughed at them. That’s what offensive. Literally the first thing in your reply to Angus was “lol”.
