Can you use ser cable for sub panel?
SER is a perfect cable for feeding power to your sub-panel, and, depending on the amount of amps their sub-panels are handling (we’ve seen everywhere from 50 amp to 200 amp sub-panels being serviced), our customers are using all sizes of SER as a sub-panel feeder.
Can you run a 100 amp subpanel off a 200 amp main panel?
Of course you can, you can add the 100 amp breaker to your 200 amp as long as it isn’t overloaded, to start adding the subpanel you must first calculate how many yards it will be from the main panel to the subpanel, there is a formula that calculates how much friction will be on the wire at the connecting distance, …
What size aluminum wire do I need for 100 amp service?
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 goes from main to 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.
What kind of wire do I need for a 100 amp subpanel?
The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)
What is #2 Ser cable rated for?
600 volts
The cable is rated at 600 volts and 90_C for use in wet and dry locations. SER cables are LEAD FREE and RoHS compliant.
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.
Can a 100 amp main panel feed a 100 amp sub panel?
Quote from the video:
Quote from Youtube video: So this is 100 amp uh it's good for 100 amps if it's being used for a service it's good for 90 amps. If you're using it for just a feeder for a sub panel.
Can you run a 200 amp sub panel off 200 amp main?
Is feeding a 200A sub from a 200A main legit? Yes, and you don’t even need another 200A breaker. The 200A breaker alread present in the panel will suffice, and so you can use a subfeed lug kit as DrSparks advises.
How do you run a wire from the main panel to a subpanel?
Quote from the video:
Quote from Youtube video: Cover then of course we're going to need our feeder wire coming from our main panel over to our sub panel and in this case we're going to be running three gauge copper.
What is SER cable used for?
SER cable is known as aluminum service entrance cable which is a type SE (service entrance), Style R (reinforcement tape) cable that is commonly used to deliver power from the service drop down to the meter base, and then from the meter base to the distribution panel board.
Does a subpanel need to be grounded to the main panel?
Most panels come with a bar joining the two, which is easily removed. Code requires subpanels to have a ground connection that’s independent of the main panel’s.
Does a subpanel need a separate ground rod?
Yes, any sub panel outside of the main building requires it’s own ground rod and a ground wire back to the main building.
What size ground wire do I need for a 100 amp subpanel?
You are correct that for a 100A feeder, the associated ground wire needs to be an 8AWG copper or 6AWG aluminum wire.
Do I need a ground rod for a subpanel in the same building?
You must, must, must, in every case run a ground ~ from the main to the subpanel. Doesn’t matter if you’re running it 3 feet, to an outbuilding or up a space elevator. You have to run a ground ~ or you are out of Code.
Can ground and neutral be on same bus bar on a sub panel?
The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.
Why do you not ground a subpanel?
So, why do you separate the ground and neutral in a subpanel? Because when we bond them together, it gives your neutral wire (the one carrying electrical currents BACK to the source) multiple pathways. That’s how the chassis of some equipment will become energized.
How do you install a ground rod for a subpanel?
Quote from the video:
Quote from Youtube video: What you're supposed to do is to ground rods at least six feet apart I did 10 feet just to conserve wire.
How far should a ground rod stick out of the ground?
You need to drive your rod all the way into the ground. The electrical code states that it must have 8 feet (2.4 m) of contact with the ground, so you need to drive it all the way down. Driving a ground rod into the ground can take a long time and can be difficult work.
Why does a grounding rod have to be 8 feet?
As a rule, ground rods must be a minimum of eight feet long and should not be cut down. In very dry ground, which provides more resistance than moist soil (meaning it does not accept electricity as readily), ground rods are sometimes stacked and joined with a special clamp so they can extend deeper into the earth.
