What Size Wire For A 100 Amp Sub Panel

Alright, buddy, let's dive into this electrical adventure! You've got a 100 amp sub panel on your hands, and you're wondering, "What size wire do I need?" Well, grab a cup of joe, and let's figure this out together.

First Things First: Ampacity

Before we start, let's chat about ampacity. It's like the superpower of your wire, determining how much juice it can safely handle. For a 100 amp panel, you'll want a wire with an ampacity of at least 100 amps. Easy peasy, right?

Enter the Wiring Chart

Now, let's consult our trusty wiring chart, the electrical superhero's best friend. It's like a secret map to the perfect wire size. For our 100 amp panel, we're looking for a wire that can handle 100 amps or more. Here's where it gets fun:

• 1 AWG - This guy can handle up to 200 amps. It's like the Hulk of wires, strong and reliable.
• 2 AWG - This one's a bit smaller, but still a powerhouse, handling up to 130 amps.
• 3 AWG - This is where things start to get a little cozy. It can handle up to 105 amps, perfect for our 100 amp panel.

So, for our 100 amp sub panel, we've got a few options. But remember, bigger isn't always better. We want a wire that's just right, like Goldilocks' porridge.

Now, Let's Talk About Voltage Drop

Voltage drop is like the tiny, sneaky villain that can ruin our fun. It's the difference between the voltage at the panel and the voltage at the outlet. We want to keep this guy as low as possible, ideally under 3%.

What is the Right Wire Size for 100-Amp Service Panel?

Length Matters

Longer wires mean more voltage drop. So, if you're running a long wire to your sub panel, you might want to consider a larger wire size to keep that voltage drop in check. It's like choosing the right hiking boots for a long trek - you want something comfy and reliable.

Safety First, Fun Second

Before you grab your wire strippers and start twisting, remember, safety first! Always follow local electrical codes and consult with a professional if you're unsure. We want this project to be fun, not a trip to the emergency room.
