Does a sub panel need a feeder breaker?
The subpanel may be equipped with a main breaker to allow for power interruption without having to go back to the main panel, but it is not required to have a main shutoff circuit breaker, since the feeder breaker back in the main panel serves this function.
What is the difference between sub feed lugs and feed through?
Sub feed lugs are a replacement set of lugs used in place of the normal main lugs of a panelboard. They allow the installer to subfeed to another panel or device. Sub-Feed Lugs can be used on main lugs interiors. Feed through lugs are a second set of lugs mounted opposite the mains end on the end of the bussing.
How do you feed a subpanel from the main panel?
Quote from the video:
Quote from Youtube video: Goes into the panel. And on to the ground burn. Everything is connected ready to heat this up at the main panel we've completed the other panel. We've completed this panel.
Is a main lug the same as a sub panel?
Main lug only load centers are typically applied downstream of a main circuit breaker panel and are often referred to as a sub panel. For main lug only load centers, the incoming cables are terminated on the line side of the lugs that are attached directly to the bus, no main overcurrent device exists within the panel.
Can I use aluminum wire to feed a subpanel?
Safety concerns caused aluminum wire to be banned from use in branch circuits years ago, but it is a common option for feeding main service panels and subpanels.
Where should feeder wires to a subpanel be connected?
Quote from the video:
Quote from Youtube video: The wire. Into the sub panel from the main panel. So we'll be running our six gauge ground wire. And our feeder wire next this is three gauge like I mentioned earlier anything six gauge or smaller.
What is a Subfeed breaker?
In panelboards, a subfeed breaker is a lug in/lug out branch breaker mounted, not on the panelboard interior bus bars, but at the opposite end of the main and cabled to the interior. They are typically of larger amperage than branch breakers mounted on the panel bus and they increas the overall panel height.
How do you feed through lugs?
The feed through lugs are located at the bottom of the first load center, and the second one is powered from there. When the main lugs above are supplied with voltage, the feed through lugs below are automatically energized because they connect to the same bus bars.
How do you install sub feed lugs?
Quote from the video:
Quote from Youtube video: One of the screws will be shorter than the other ones this screw will be used to attach the neutral lug to the panel board remember the lug doesn't matter but the screw does.
When can I use a main lug panel?
Main lug load centers are sometimes referred to as add-on, secondary or downstream panels. These panels are added when all circuit slots in the main breaker load center are full or when a remote panel is desired.
What wire do you use for a sub panel?
The cable you run from the main panel to the subpanel also depends on the amperage rating. You can use 10 AWG, three-conductor wire for a 30-amp panel, but for a 60-amp one, you need 6 AWG wire. If you’re installing a 100-amp panel, you need 4 AWG copper or 2 AWG aluminum three-conductor cable.
Can you install a main breaker in a main lug panel?
Main breakers can be installed when the meter and feeder cable are within 10-feet of the panel. Consult your local codes to see if your panel will meet this or another requirement for proper installation. Main lug panels do not have a main breaker.
Can I use aluminum wire for a 100 amp subpanel?
If you decided to use aluminum wire for your 100 amp sub panel, you should therefore use #2 aluminum wires to avoid malfunctions such as short circuits that may cause electrical damage to your components.
What is the disadvantage of using aluminum wire?
Aluminum Wire Pros and Cons
The downside to aluminum wiring is that it’s vulnerable to corrosion and therefore cannot match the lifespan of copper wire. Likewise, its softness makes it prone to breakage and loose connections.
What gauge wire do I need for 100 amp service?
Installation of 100 amp electric service or subpanel needs a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire inside a minimum 1.25 inch, schedule 40 or 80 PVC electric conduit for underground service.
Can a 60 amp breaker feed a 100 amp sub panel?
You can feed a 100 Amp panel with a 60 Amp breaker. Keep in mind that the sub panel needs to be rated above the breaker size.
How big of a subpanel can I install off a 100 amp service?
Let me try and answer some of your questions. First the panels you are looking at that are rated 100A simply means you can use them for any application up to 100A. You can for example add a 60A breaker to your existing panel and protect the new subpanel with a 100A rating.
What size wire do I need for 100 amp service 50 feet away?
For 100 AMP service, you’ll need a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire. Make sure to limit your voltage drop to 3% regardless of distance.
What wire do I need for a 60 amp subpanel?
In short, the wire size for a 60 amp sub-panel 150 feet away is 3 AWG gauge wire.
What size wire do I need for 100 amp service 100 feet away?
If you check the wire size chart (you have the link in the introduction), the #0 AWG wire (also known as 1/0 AWG wire) has 150 ampacity. That means that #0 AWG wire is the perfect size wire for 100 amp service 100 feet away.
