No it is not and by saying that you also say that the 90 day report is a visa.
The date they want is the date in your passport of the "Permission to stay until" stamp.
STAY visa is the keyword. There is nothing from a 90-day report receipt that you need to fill in when you do a new one.
You have obviously never done a TM47 90-day report online.
You are asked for 2 dates, "Arrival Thailand Date" and "Stay visa expires" , the latter being the date your "permitted to stay until" stamp in your passport indicates.
They will loosen up again, sorry to be repetitive but you are using a flat lug that will have a very limited contact surface with the switch.
It doesn't bottom out so the pressure on it will deform its side edges with time and that is when it get loose again.
Don't ask me how I know this..
I know exactly what you're experiencing, I have two grand children living with us and they have each their own room..
Me: Not a degree below 27 on the remote or I'll cut down on your candy and your school money!
My way of doing it in the battery room under the house.
50sqmm feed, switch, 35sqmmx2 to the250A fuse and the busbars.
Two battery stacks of each 4x5KWh (=40KWh) connected to the busbars.
That is flat lug and it should only be used in a switch that has a flat bottom, not a round bottom like your switch has.
Its connection to the switch is only on the side edges when you use it as you do
Looks like you are using some kind of lug on the wires, maybe DZ47/C45 lugs like this:
the switch however is intended for bare wire which you can see from its rounded bottom.
I use DIN-rail enclosures for all my other switches but the battery DC switch I used is this one:
it has proper M8 hex bolts and not weak Philips type screws..
That means that you can temporarily overload your meter up to 50++ Amp somewhere above that your fuse will trip but your meter could withstand up to 100A (before it heats up so much that it starts to spin slower ☺️ )
