What's going on my friends this is Dustin Stelzer with Electrician U and today we're going to talk about home-runs
Alright, so what is home run? We think like baseball
No in the field when electricians are talking about a very specific piece of wire,
conductor, or cable
Wherever we are going from the electrical panel out to a circuit, that one piece of wire
basically, the one that leaves the breaker goes up somewhere
and comes down to the first device in a circuit that's called the homerun
Because from the first place in the circuit that goes home
Home is the panel panels home. So we say it's a homerun
There's a lot of different terms. Somebody emailed me. That's the reason I'm going over this. This is a very basic topic, but
somebody's like I just don't understand the difference between like service entrance conductors and multi wire branch circuits and
You know like
regular branch circuits feeders and why are some things home runs and some aren't? It's actually a good question for an apprentice
To not know is like pretty common
so here's what it is a service entrance conductor is the wires that come in from outside of the building and
Come into the service the you know meter and the main disconnect
from there from the the breaker inside of there - any other panels
Anywhere else that there's a breaker or another disconnect essentially, is called a feeder
so it's between a breaker and another breaker or between a
Disconnect and a breaker and a breaker to disconnect and dissident in the disconnect. That's a feeder
It's feeding something then a branch circuit is last branch circuit is pretty much what you think of like a tree everything branches out
Right. So from the last sub-panel or from any sub-panel, really?
Even service panels you may have circuits that go out to one device and then branch out to multiple other devices
Those are called branch circuits. The only difference between a branch circuit in a multi-wire branch circuit
Is that in one cable assembly you might have multiple circuits versus in another cable assembly
you might only have one circuit so like 12/2
Romex is just a black and a white and a ground on the inside of that
That's just feeding one circuit
But you might have a 12/3 or 12/4 where you've got black, white, red,
and a ground. Or you have black, white, red, blue, and a ground all in the same cable assembly
So that's multiple circuits that you're able to run in that one cable
So we call that a multi-wire branch circuit instead of just a regular
Branch circuit. So I hope that makes sense
Service entrance conductors come into the service. Feeders go from the service to other panels
Maybe some transformers stuff, you know weird with disconnects weird things like that
and then FROM
those panels outward to all of your devices are your branch circuits?
The only one of those that is a home run is any wire that comes from a panel
to the first device in a circuit. If you have 10 to 15, you know
receptacles in a room all of those are not called home runs all of the ones that go between devices are called hot jumpers.
Only the one that goes from the very very first device all the way back over to your panel and hooks up to a
breaker, that is called your home-run. Hope that clarifies some things. Thank you guys so much for watching. I'll see you in the next one.
