Mine will do that in response to stress or randomly. My house builder had same thing that gradually became worse until he blacked out in the shower and was resuscitated with an adf shock. Two days later he was the proud owner of a pacemaker. Go see a cardiologist wherever you live and they may give you a monitor to wear for a month or two. The events usually pass quickly so by the time you get rigged up it is over, one way or the other, and without the monitor the doc won’t know what is going on for sure.

Here is a simple user test to determine how long the ups will allow the cameras + nvr to function. Get everything installed, charged up, and verified to work. Then, turn off power to the system and let the ups do its job. Start your timer. Note the duration when the system starts failing. Done.

At least there was a spot for a 3mm tip in the plastic case in the picture.

Yeah, yeah, i know . West meets East. Lol.

Find a licensed electrical engineer to design your system. Or possibly a master electrician from a reputable firm familiar with the code requirements.

What are the amps and number of phases/poles for the major devices ? Ovens in the US are typically hard wired ( no plug) , 2 120v phases, and require a separate breaker. Good idea to put microwave on dedicated circuit, 20 amp (US) as you don’t want to have two high current users on same circuit and trip the breaker repeatedly leading to a weak breaker over time. Dishwasher may pull 10-15 amps and is another candidate for a dedicated circuit. Other than that, i think our rule of thumb was no more than 6 plugs per breaker for typical low-moderate current plug in devices. Any plug within 6ft of water had to be gfci.. that being said, code may have changed and you should do some research in the local electric codes.

From what i could see of the tips, was the H3 too small and the 1/8 hex key , i assume on the cluster, also too small ?

Or a 3.2 mm Allen. That is a rare beast.

Forgot that. Now all we need is an inside caliper ….

Likely a 3.5 mm hex key socket given that it is between the two T sizes.
