@andremantovani4 жыл бұрын
nice! the thing with the current transformer (ct) clamps to be connected FIRST on the monitor and then on the mains is due to CTs might build up a high voltage on their secondaries if they are open.
@Bob-ww4mk3 жыл бұрын
I suspect the current probes need to be connected to the monitor first because these clamp-ons are likely current transformers. The clamp-on core makes a magnetic path between the coil on the inside and the one wire 'coil' on the outside. They produce a current proportional to the current they are clamped to. So now the voltage on their open wires (assuming you forgot to plug them in first) is I times R. Where I is the current they are sending back to the monitor unit and R is the resistance of the open wires. A small I times infinity is a large number of volts on those open wires. Certainly not infinite volts and maybe not a lot of current, and isolated from other grounds, but it might change your train of thought if you got your fingers on it. Once connected, the monitor unit provides a few hundred ohms of R and the I times R value is manageable for the monitoring circuits and less startling to you. I love your videos. I know everything about everything but oddly I've learned a lot by watching.

Tandem breakers are not usually 240V, they provide 2 120V circuits. I believe the Sense needs to connect to both 120V (ie 240V) phases to work correctly.

You can get 240-volt tandem Breakers. There are actually four individual breakers on the setup and to inside Breakers are tandem and the two outside Breakers are tandem giving you two individual 240-volt Breakers in a space where you normally would have one 240 volt Tandem breaker. I have used these and they are very helpful in limited space boxes.

Only issue I expect to run into is my Main Square D QO Panel is virtually maxed out of slots on the Neutral Bar (Lots of doubled up spots. One with a single connection would have room for a second wire... But it is somewhat buried alongside the other wires in the panel.). Thinking if the Monitor doesn't need the Neutral for "Monitoring" purposes I could more easily "Piggyback" into an existing Neutral Connection (the same one I'd be sharing the Neutral bar with anyway... Just via a 3 Lever Wago, that connects to my Video Doorbell Transformer.).

I would be surprised if it would be acceptable when installing two wires on one terminal, if they are different sizes. For example, one #14 wire and one #10 wire (one on each side) I would think you could possibly have the smaller wire not having the same torque pressing down on it as the #10 just because of the angle created by the two different wire sizes. Does that make sense? Personally I would want to use the two-pole 15 just for the sense meter. I get it that you could be pressed for space but I would exhaust the twin breakers first. But, that's just me.

I'm not sure about this as far as the square and sine wave but the FAQs appear to say don't use the solar sensors for should not be used for generator.

Nice catch! I am impressed that you noticed! You're correct. My original Sense unit is outside in the first panel on the property. That way it can monitor all of the electrical usage on my property including the well which is fed from that outdoor panel. The problem with that outdoor one is that it isn't the best example of how to install Sense and it wouldn't apply to as many people. That is why I decided to install Sense in my regular panel just for the sake of making this video. I might make a proper "how to install Sense outdoors" video sometime but I didn't want to promote the way I installed it out there. It has been working perfectly though for almost two years and you are right that I did put it in a bag to hopefully help protect it from moisture. Also, the ambient conditions here in MN can get nasty at down to -30 degrees so that is well below the minimum 5 degree recommendation. The instructions actually say 32 degrees but a guy from their support team said it should be fine down to 5 degrees as long as it is installed while it is above 32. I'm sure my unit won't last as long out there but it is worth it to me to be able to monitor the well. Thanks for the comment!
