What is it and what's it doing in my electrical panel?

What is this thing? There are 2 of them in the panel!



Bypass capacitor. One for each incoming line.

Looks like a capacitor.
Direct Current too.

Would have said doorbell, but 1000 watts is like 10 amps.

Beat me on capacitor but what is being bypassed Mike?

W.V.D.C. is working volts not watts.

It is a noise filter.

Can’t tell from the picture, but bypass capacitors are typically used to allow RF powerline devices to function properly.

Thanks Guys,

This house had audio speakers mounted everywhere so I believe Michael is right…
noise filters.

Thanks again
