As an inferior circuit breaker, a subpanel disperses electricity to certain areas or dwellings. It functions as a simple power distribution panel. Having a subpanel in your building is the way to make everything work properly.
You need to know how many subpanels you need for your dwelling for the service to run properly. This will prevent the subpanel from being overloaded. So, how many sub-panels can you have on a 200 amp service? As an example, consider the main panel with 200 amps. The number of subpanels can be added, provided the communal electrical demand does not exceed 160 amps.
If multiple circuits run simultaneously, the electrical service might get overwhelmed. To avoid exceeding the maximum amperage, you’ll need to plan carefully and pay attention to the sub-panels you add. In this article, we will show you what subpanels do, how to add them to the main panel, and why they’re important. When adding the sub panel, be aware of the amount being added. Thankfully, this guide will help you along the way. Let’s begin!
What Is A Subpanel?
Subpanels are typically electrical panels with a capacity of fewer than 200 amps. It includes around 4-12 breakers, powered by a 240V circuit breaker from the central panel. Essentially, the feeder breaker is the main panel here. Nonetheless, you can connect a 200amp subpanel with a 200amp feeder panel if the load is no more than 160 amps. Unlike the main panel, the subpanel does not have a main shutoff circuit breaker, but neither does the main panel. They both have two hot bus bars, as well as neutral and ground bus bars.
Why Is The Subpanel Necessary?
The two most common uses for sub-panels are:
- The main breaker panel may not be able to accommodate additional circuits. In that case, the main panel would be full of breakers.
- In order to regulate the circuit closer to the service area, which might be a house or apartment.
- A subpanel is also useful to supply power to a room addition if it is only required to accommodate additional circuits being placed closer to the main panel.
An Overview Of Connecting Subpanels
Connecting a subpanel to the main panel is accomplished with a feeder cable. The feeder cable has three conductors: a copper ground wire, an insulated conductor, and an insulated ground wire. A feeder cable is fitted with two hot wires that must be attached to the lout placed on the hot bus bar included in the subpanel.
A copper grounding wire must be connected to the grounding bus bar, which is located in the grounding box. You need to connect the wires from the main panel to the hot feeder wires. The ground and impartial cables come from the feeder cable and connect them to the bus bars. After that, the hot feed wires are fastened into the dual-slot feeder breaker within the main panel. It is now time to add circuits to the subpanel.
Number And Capacity Of Subpanels
As soon as a subpanel is built, you must address two issues regarding capacity:
- In order for a subpanel to be functional, it must have the proper amperage capability for the circuits and rooms it serves.
- It is important that the main service should be large enough to accommodate the additional power occurring from the sub-panel. The old main service requires a replacement before establishing subpanels.
Symptoms Of An Overloaded Electrical Circuit
The following symptoms happen when an electric circuit is overloaded:
- Circuit breakers trip frequently
- Wall Plates appear faded or hot
- Lights dimming, blinking, or flickering
- Fuses that frequently blow out
- Levers or other appliances give you a mild shock
- Switches, receptacles, and appliances make cracking, stuttering, or buzzing noises
- A burning smell coming from wall switches or outlets
If you experience any of these problems, you’ll need to detach some subpanels. Overloading a circuit may cause all the appliances attached to it to malfunction.
Verifying If One Of The Panels Is Maxed Out
An amperage test using a multimeter can be convenient here. If the amperage of a wire is low, then the current is sufficient. To get the right amperage, you should turn on all the equipment as possible. If it appears that there is an overload, but it does not reflect on the meter, it is likely that there is. You can check with the manufacturer to see if they have adequate warning systems.
The Purpose Of A Subpanel
A subpanel is an additional electrical circuit installed in a building to provide supplemental power. This is often necessary in areas where there’s a shortage of regular electrical outlets or in cases where the regular wiring isn’t strong enough to handle the increased load.
The purpose of a sub panel is to distribute the extra power so that it can use by all the devices in the building equally. This way, no one device gets too much power and becomes overloaded – which could lead to damage or even injury.
When selecting a sub-panel, consider the size and type of needed panel. The size will depend on how many outlets need, while the type will depend on what wiring uses (RJ-45, UTP, etc.).
Warning Signs Of An Electrical Circuit That Overload
A 200 amp service can usually handle up to six sub-panels, but it’s always a good idea to check with your electrical contractor to make sure. Any more than six and you could run into problems like unstable voltage or heat buildup in the panels.
If you have more than six sub-panels, ensure that each one is properly wired and attached to the main panel. Also, install a ground fault circuit interrupter (GFCI) if there is any chance of exposure to water or other potentially hazardous materials.
Checking If A Panel Is Max Out
Most standard residential electrical panels can handle up to 100 amps of load, but it’s important to check your panel’s capacity before overloading it. If you’re unsure about your panel’s capacity, you can use an online tool like the one below to find out.
To use this tool, enter the address of your home and click on the “Check Your Electrical Panel Capacity” link. The tool will then show you a list of all the electrical panels in your neighborhood and their respective capacities. It will also tell you how many amps each panel can handle.
How To Determine Subpanel Loads
There is no set number of subpanels that can install on a 200 amp service, as the load capacity of each panel will vary depending on the size and type of the panel. However, it generally advises installing at least one subpanel to handle the peak loads expected during an emergency or storm.
The main panel, along with sub-panels, can contribute to accomplishing multiple tasks, especially when the main panel does not have the space for additional circuits. Adding sub-panels to a circuit will not set a limit to the amount of power that can be supplied, but the combined power must not exceed 160 amps when using a 200 amp main panel. Follow these instructions to properly install subpanels. I hope now you understand how many sub-panels can you have on a 200 amp service.
What Are The Benefits Of Having A Sub-Panel?
There are a few benefits to having a sub-panel. One benefit is that it allows you to add more capacity to your service without adding extra wires or poles. Additionally, a sub-panel can help reduce the number of switches and breakers needed in your home.
How Many Individual Sub-Panels Can You Have On A 200 Amp Service?
A 200 amp service can have up to two individual sub-panels.
How Do I Connect To A Sub-Panel?
You will need the wiring diagram for your home and the appropriate connectors to connect to a sub-panel.
What Are The Limitations Of Having A Sub-Panel?
One limitation of having a sub-panel is that it cannot use to expand your service beyond 200 amps. Additionally, the sub-panel could become unusable if there are any problems with the wiring in your home.
Is There A Fee For Having A Sub-Panel Installed?
There is typically no fee for having a sub-panel installed.
I am passionate about tools and electric work. I love finding new tools and experimenting with them.
