For a 80 amp you need a 4-gauge copper wire. For a 100 amp service, you will need a 1-gauge wire.
Will 8 gauge wire work with 1000 watt amp?
For up to 500 watts RMS, 8 gauge is sufficient. In the 500 – 1000 watt RMS range, you want to run 4 gauge. From 1000 – 1500 watts RMS you should be running 2 gauge.
What's bigger 4 gauge or 8 gauge?
What is Wire Gauge? The thickness of a cable or wire is defined by its gauge size. The general rule of thumb is that the smaller the gauge number, the thicker the cable.
Can I use 8 gauge wire on a 15 amp breaker?
You're always allowed to use bigger wire
The circuit ampacity defines the minimum wire size needed. If you have larger wire on hand, go ahead and use it. For instance I often run single appliance circuits that demand a 15A breaker.
How many amps can a 50 amp breaker handle?
A 50 Amp split phase 120/240 VAC service should be capable of 50 Amps per leg for a total ampacity of 100 Amps.
Can I use a 50 amp breaker?
3 Answers. In general, no. Installing a 50A breaker on wiring only designed to support 40A is dangerous and can result in a house fire.

50-amp 240-volt circuit: 50 amps x 240 volts = 12,000 watts.
Can I run a 30 amp dryer on a 50 amp breaker?
Yes. Assuming the wire running from the breaker to the dryer is rated for 50 amps. The circuit breaker's primary function is to protect the wire, not the downstream device. The dryer should have built in overcurrent protection, and if there is a short circuit, you will be protected with the 50 amp breaker.
Can you use 6 wire on a 40 amp breaker?
The minimum wire size you can use with a 40-amp circuit breaker is 8-AWG. You can use larger gauge 6-AWG wire for future-proofing, but a lower gauge wire will render the electrical system non-compliant with the NEC.

The industry standard for an electric stove is a 50 amp double-pole circuit breaker.
Can a 60 amp breaker feed a 100 amp sub panel?
You can feed a 100 Amp panel with a 60 Amp breaker. Keep in mind that the sub panel needs to be rated above the breaker size.
What size wire will fit in a 100 amp breaker?
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.
Can you run a 100 amp sub panel off a 100 amp main panel?
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 I use #8 wire for a hot tub?
All 220v spas require a 4 wire connection from your main circuit breaker panel. Some spa manufacturers require a 60amp breaker. Although some manufacturers state their spas can use 8 guage wiring for a 50amp circuit, we recommend 6 gauge wiring on all 50/60 amp installations.
