It’s up to you. You can use a single pole breaker or double. Single has potential to be cheaper. If you don’t plan on maxing out the outlet and the RV at once, you could safely go as cheap as a single pole 30A breaker 10-2 wire for the run and a 30 A panel if you can find one that small.
Does a sub panel need a feeder breaker?
If the main panel’s MAIN breaker is of a size that will adequately protect the feeder wires and the subpanel, then no breaker is needed.
What size breaker do I need for a sub panel?
Based on your question, since you will be having a subpanel, you want the breaker feeding the subpanel to be sized for the subpanel or slightly smaller. So if you purchase and install a 200A subpanel, then the breaker should be 200A. If you use a 125A subpanel, then use a 125A breaker.
How do I know if I need a single or double pole breaker?
Single-pole breakers are typically used for low-power appliances, as they can provide 15 to 20 Ampereges and 120 Volts. Double-pole breakers protect heavy machines, as they can provide 20 to 60 Ampereges and 240Volts.
Can you feed a panel through a breaker?
If the wire size from the sub panel is the size that the main breaker in the panel being fed from you don’t have to have the breaker but this means if you have a 200 a main breaker in that panel the wire ampacity will need to be that large.
What wire do I need for a 100 amp subpanel?
Want to know the short answer? A 100 amp sub panel wiring size requirement is #4 for copper wires and #2 for aluminum wires. Now, you may question what you should use for your wiring installation and what are the advantages and disadvantages of one wire type from another. We’ll discuss these issues below.
How do you feed a subpanel from the main panel?
Quote from Youtube video: So here we can see the circuit that we brought over this one right here is to create space in the panel. And this one is for the sub that feeds the sub. So we got to feed our new 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.
Can a 60 amp breaker feed a 60 amp sub panel?
Probably not. While the 60A breaker’s primary job is to protect the wiring between the panel and the subpanel, you can have breakers totaling more than 60A in the subpanel.
Does a 60 amp sub panel need a main breaker?
Your subpanel does not need a main breaker if it’s in the same building. If it is in an outbuilding, you need a disconnect switch, and the breaker will suffice but its size doen’t matter.
How many breakers can I run off a 60 amp sub panel?
The NEC does not allow installing panels rated below 100-amps as the main electrical panel for the house. Modern 60-amp electrical panels are purpose-built as sub-panels and generally only have 8 to 10 slots available for circuit breakers.
Can you feed a 100 amp sub panel with a 50 amp breaker?
Just wire it up. There is no problem using a sub panel that can take more current than you will ever feed it. Points to note: The cable to your hot tub will be rated for 50A (not 100A); therefore you must not upgrade the breaker in your main panel to 100A.
What is the 6 breaker rule?
The “rule of six” refers to how many breakers or throws it takes to disconnect a building from the electrical supply, so if you have more than six breakers in a box at your service entrance there needs to be a disconnect upstream of it, either in the panel or upstream.
Can you connect a subpanel to a subpanel?
Answer: Yes. The main electrical service panel is where branch circuits originate. A branch circuit consists of the circuit conductors between the final over-current device protecting the circuit and the lights, receptacles and equipment supplied by the branch circuit.
How do you wire an outdoor subpanel?
Quote from the video:
Quote from Youtube video: And backfilled it was finally time to wire up the sub panel for the soap shed. And officially juice it up it took a little time working the large gauge wiring into the panel.
Can two wires go on one breaker?
When it’s NOT a defect: Double tapped wiring is ok if the circuit breaker is designed for two conductors. If a circuit breaker is designed for two conductors, it will say so right on the circuit breaker, and the terminal of the circuit breaker will be designed to hold two conductors in place.
What is a piggyback breaker?
A double circuit breaker takes the space of a single circuit breaker on a panelboard. Depending on local customs, they are called duplex, slimline, twin, half-height, half-inch, double and waferbreakers.
Why would you double tap a breaker?
A double tapped breaker is basically two wires under one circuit breaker that is designed for one wire. You can see what this looks like in the picture above. The issue with double tapping is you could technically have a loose connection or an overloaded breaker since the breaker is not designed for two wires.
