Three phas ain't nothing to fuck with...
It's worth paying a professional to come out and make sure it's shut off at the box, and then at least capping the end.
Honestly you want to remove the whole run.
But you absolutely need to make sure no power can ever go thru it, don't just leave a breaker flipped to off and call it a day. I believe they can "blank it out" by removing the breaker which prevents a load from ever going down the wire.
You called it; I just have the breaker flipped. I’ll make sure to get this taken care of ASAP then.
I’d cut the conduit back a foot and mount a 4x4 box. I’d then cap the wires in that with marretts. Everything would look professional and safe.
I’d also test the shit out of those wires to make sure there is no voltage.
Thanks! I’ll probably install an outdoor box, then. I’ll make sure there’s no current; I do just have the breaker flipped, but I have a couple of testers that should be able verify there’s nothing flowing. It does frighten me seeing that and knowing it’s three-phase.
North America- Most houses don’t have 3 phase. It’s an odd thing for a residential house. Large Apartment buildings yes. My in-laws had an attached work shop and they had to pay to have it brought down their street. Saying all that, 230v can easily kill. Same with 110.
Removing the breakers and capping the wires inside the panel is easy and not expensive if you get an electrician to do it.
Safest way for you to do it is to kill the feed to the panel so there are no live wires inside. Then disconnect and cap them.
