What is this cable in my yard, why is it exposed, and what can I do about it?

That is a Homac 600V rated splice so it's probably part of your electric service. I would be calling the power company right now and report a dig in to an exposed service or secondary lateral. Stay ...

How do I feed an ethernet cable through a doorway without damaging the door or wall?

You can buy flat Ethernet cables. I'm betting you could get one under the door and still allow it to be closed. Another option is a powerline Ethernet adapter. This is a set of modules that plug into ...

How can I know if one extension cable and outlet can handle so much electricity use?

The four pumps will require 9.2 amps. Your outdoor outlet has a breaker that's either 15 or a 20 amps so if nothing else is on the circuit, you'll be OK. If you have other stuff plugged into that ...

The OEM cable does not have a ground or earth connection. The cable on the right does. So this will be a safe replacement for the original cable. The ground connection will not be used and that wire ...

Is twisted and taped splice on cable, objectively any less stable than wire-nuts or terminal blocks?

Splice connectors such as US-style wirenuts and UK style terminal blocks are demonstrably better in nearly every way to the twist-and-tape method you describe. Wirenuts and terminal blocks are more ...

A small hole is totally adequate for this purpose. If you drill neatly then a grommit is not needed. A ~3mm hole might be sufficient, just measure your wire first. A small beauty plate may help to ...

Can I run CAT6 FTP cables parallel to electrical cable in the same conduit?

Absolutely not. Low voltage (LV) and mains cannot share a conduit. Further, you cannot attach anything else to the outside of the electrical conduit. So forget about ty-wrapping the LV cable to the ...

An easy solution if the slat-to-rail interface allows is to put a pin (or loose fitting nail) into a hole drilled through the end of one slat into the frame, on both ends of that one slat, in the ...

You can run cables parallel outside conduit. Ideally a few inches apart but in practice right next to each other is usually OK. But you can't run them together inside conduit. Plus, inside conduit ...

Is twisted and taped splice on cable, objectively any less stable than wire-nuts or terminal blocks?
