Ad says its sized to fit inside those panels. Not that its sized to handle those loads.
In fact it doesn't seem to handle any load at all. I thought maybe someone was mistaken but sure enough this is what the ad says:
One lead connects to an existing breaker, the other to neutral bar. That's it!
Connected that way, if you know anything about electrical panels, the breakers are hot and the neutral is the utility ground that completes the circuit, in other words if it was a wire it'd be a short. Now since nobody has said anything about these things glowing red hot before bursting into flames I'm gonna go out on a limb and say its not a wire.
But also, the size or number of circuits or even the panel can't matter because it doesn't have any current flowing through it. What it almost certainly does have however is something that shunts any and all noise riding on the AC line to ground.
Its interesting its wired to neutral and not ground. Three wires come into residential panels- two hot and one neutral. In addition to this we are required to add an earth ground. I notice they do not say to wire to earth ground. Also notice they do not require connecting to both incoming legs. Well, all circuits from either leg are completed by connecting to neutral. So if the goal is line noise then connecting one leg to neutral in effect connects everything in the house. This is why flipping breakers off improves sound even when its circuits with nothing connected or running. The wires themselves even with nothing running are antennae feeding RFI into the system.
All the review comments so far sound to me exactly like what I get when I go flip off all the breakers. Noise floor drops dramatically, grain and glare disappear, everything just sounds incredibly real.
So Frank you're gonna put one in tomorrow. Got to flip the breakers off anyway. Only take a few minutes to flip them all off except the system, see how it sounds. To compare no breakers before to breakers Gate after. Be very interested to hear what you hear. Very interested.
