What is the size of a connector for 100 amp service?
When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.

How many amps can a 100 amp panel handle?
How Many Circuit Breakers Can a 100 Amp Panel Handle? For safety, check the instruction of your panel to see how many breakers it can handle. Typical 100-amp panels have 20 circuits, meaning they can handle 20 full-sized breakers.
How many ground rods do I need for a 200 amp service?
#4 grounding
for 200 Amp services, a #4 grounding electrode conductor (ground wire) is required.
What kind of wire for 100 amp sub panel?
What Size Wire for 100 Amp Sub-Panel? 1 3 gauge THHN Copper Wire 2 Needs to be buried in a conduit 3 most popular
Can a 2 / 0 copper feeder be run to a 200 amp subpanel?
This section also allows any feeders that carry the entire load of the dwelling to be sized the same way, therefore, a 2/0 copper can be run to a 200 amp subpanel as long as that panels carries all the load. Explain this please? Click to expand…
How big of a conductor do I need for a 200 amp panel?
The code states that you can use 83% of the service size to size your service conductors. So a 200 amp service would require a 166 amp conductor- 2/0 copper is rated at 175 amps at 75C so it can be used as the service conductors.
How are feeder breakers in a distribution panel sized?
I always assumed that breaker to just be sized based on total load in the panel plus 125% so taking the connected load of all the branch circuits in the panel and adding 125% to come up with the breaker size to feed the panel.

Can a 100A feeder be raised to 1 cu?
If the answer is no I want to use the full 100A then you feeder would have to be raised 2 sizes to make up for the voltage drop to a #1 cu or 1/0 al. If the answer is yes then you will be able to stay at the original size. The main reason for you to consider this is the cost of material.
