For a 120/240 volt sub panel at a full 100 amps at 600 feet you will need a 250MCM copper conductor. This conductor is rated at 265 amps with 90 degrees C insulation for normal distance installations.

Can you run 30a per phase on a 100a panel?

No, you should not load a panel beyond its rated capacity. In this case, a 30A load per phase in a 100A panel would exceed its capacity and could cause overheating or other safety hazards. It's important to properly size the panel based on the expected load requirements.


What is the difference between a 60A service and a 100A service and how is the difference recognized?

The difference is the difference in the size of service entrance conductor and maximum ampacity of the service equipment [panel].The panel will be labeled and the main breaker, if there is one, will say 100 on the operating handle.It is unlikely you will find a sixty amp service unless it has fuses [probably with pull-outs] and cloth service cable [it will be very old]. Many of these old fuse services may be 100 amps.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.


Can you upgrade a 100A main circuit breaker to a higher amp?

I doubt if the 125 amp breaker will fit into a 100 amp box. This is due to the rating of the box only being rated at 100 amps. If this exchange could be made then the service conductors feeding the box must be upgraded to take the 125 amperage that the breaker will allow on the conductor.


What size of wire do I need for 130 ft run sub panel?

Wire sizing is based on the amperage of the load. Without this amperage the wire size can not be calculated. Also with sub panels it should be stated whether it is under the same roof as the main panel or separate from the main building. Different code rules apply to each application.


What is the largest sub panel you can install off from a 60 amp main panel fed by 100 amp service?

You can install a 100 amp sub panel off a 60 amp main panel fed by 100 amp service. This allows for the sub panel to be adequately powered with headroom for future circuits or expansions. It is important to ensure the wire size from the main panel to the sub panel is sufficient to handle the load.

What are the necessary steps for installing a garage sub panel?

To install a garage sub panel, you need to first determine the appropriate size and location for the panel. Then, you will need to run a conduit from the main panel to the garage, install the sub panel, connect the wires, and properly ground the panel. Finally, you will need to test the panel to ensure it is functioning correctly and safely.


What is the recommended size for the main breaker in a residential electrical panel, specifically for a 125 amp main breaker?

The recommended size for a main breaker in a residential electrical panel with a 125 amp main breaker is typically 150 amps.


Do you need a main disconnect on the feeder wires running to a detached garage running from the box in the house?

Yes you do. The detached garage will either be fed with a single circuit or a sub panel. The wire feeding the garage will need to be protected and that is the purpose of the breaker (disconnect). The breaker size will be determined by the size of the wire that is used on this circuit.


What wire size do you need for a 125 amp panel with a 100 amp main breaker?

A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.

How can I add an electrical sub panel to my existing electrical system?

To add an electrical sub panel to your existing system, you will need to first determine the appropriate size and location for the sub panel. Then, you will need to obtain the necessary permits and follow local building codes. Next, you will need to shut off power to the main panel, install the sub panel, and connect it to the main panel using appropriate wiring and breakers. It is recommended to hire a licensed electrician for this task to ensure safety and compliance with regulations.
