Are you looking for a reliable and easy-to-follow guide on 100 sub panel wiring diagram? You have come to the right place. In this article, we will provide you with everything you need to know about wiring a 100 sub panel, including the materials required, step-by-step wiring guide, tables, and FAQs.
What is a 100 Sub Panel and Why Do You Need it?
A 100 sub panel is an electrical panel used in residential and commercial buildings to distribute power to different circuits. It is called a sub panel because it is connected to the main panel via a feeder cable and is used to power secondary circuits in the building. A sub panel is necessary when the main panel is located far away from the circuits it powers or when there is a need for more circuits than the main panel can accommodate.
If you are planning to add more electrical devices or appliances to your home or office, you might need to install a 100 sub panel to meet the increased power demands.

Step-by-Step Wiring Guide for 100 Sub Panel
Follow these steps to wire your 100 sub panel:
Step 1: Turn Off the Power
Before starting any electrical work, make sure to turn off the main power source to avoid electrocution. Use a voltage tester to confirm that there is no power running through the wires.
Step 2: Install the Sub Panel
Mount the sub panel on the wall where you want to install it. Run a feeder cable from the main panel to the sub panel location. Make sure the cable is long enough to reach the sub panel and leave some slack.
Step 3: Install the Grounding Rods
Drive two grounding rods into the ground near the sub panel location. Connect the rods to the sub panel using a bare copper wire.
Step 4: Install the Circuit Breaker
Install the 100 amp double pole circuit breaker in the main panel. Connect the feeder cable to the breaker and tighten the screws.
Step 5: Connect the Wires
Strip the insulation from the feeder cable wires and connect them to the sub panel. Connect the black wire to the hot bus bar, the white wire to the neutral bus bar, and the green wire to the grounding bus bar. Tighten the screws to secure the wires in place.
Step 6: Connect the Grounding Wire
Connect the bare copper wire to the grounding bus bar in the sub panel. Use a green grounding screw to secure the wire in place.
Step 7: Install the Circuits
Install the circuits in the sub panel using PVC pipes. Connect the wires from the devices to the circuit breakers in the sub panel. Use wire nuts to secure the wires in place.
Step 8: Turn On the Power
Turn on the main power source and test the circuits to ensure they are working properly.
FAQs
1. What is the maximum number of circuits a 100 sub panel can accommodate?
A 100 sub panel can accommodate up to 24 circuits. However, the number of circuits may vary depending on the size of the panel and the power requirements of the devices or appliances.
2. Can I use a 100 amp sub panel for a residential property?
Yes, a 100 amp sub panel is suitable for a residential property. However, it is important to ensure that the sub panel is not overloaded by too many electrical devices or appliances.
3. Can I wire a 100 sub panel myself?
Yes, you can wire a 100 sub panel yourself if you have some electrical knowledge and experience. However, it is recommended to hire a professional electrician for safety reasons.
4. How do I choose the right size of sub panel?
The size of the sub panel depends on the power requirements of the devices or appliances you intend to power. A 100 amp sub panel is suitable for most residential and small commercial properties. However, if you have high power demands, you may need to install a larger panel.
5. What is the difference between a sub panel and a main panel?
A sub panel is connected to the main panel via a feeder cable and is used to power secondary circuits in the building. A main panel is the primary panel that distributes power to all the circuits in the building. The main panel is usually located near the electrical meter.
Now that you have read our comprehensive guide on 100 sub panel wiring diagram, you should be able to wire your sub panel like a pro. Remember to follow all safety precautions and consult a professional electrician if you have any doubts or concerns.
