How far can a subpanel be from the main panel?
You must provide from 3 to 4 feet of clearance on all sides of the panel depending on the voltage to ground. You may not know this voltage, so it’s best to provide 4 feet. The panel must be easily accessible, so don’t install it too far above the floor; 4.5 to 5 feet is about right.

Safety concerns caused aluminum wire to be banned from use in branch circuits years ago, but it is a common option for feeding main service panels and subpanels.
Do sub panels need to be grounded?
The sub panel neutral bar or terminal should not be bonded to the enclosure or the ground of the sub panel. The sub panel ground should not have a ground rod tied to it. The bonding for the main ground sources such as a ground rod is made at the main panel where all the grounds are bonded together as well.
How far can a sub panel be from the main panel?

Can I have 2 main electrical panels?
If you are in the US, then the answer is yes. The main electrical drop has to be sized for both panels and each panel should have its own utility meter. All NEC codes must be conformed to. You need to consult your local government to see about local codes as well.

What is Noalox used for?
NOALOX is an anti-oxidizing compound that helps prevent the formation of oxides on the outside of a conductor.
Can you put a 100 amp breaker in a 100 amp panel?
The 100 Amp panel has a 100 Amp breaker. If you want to have 100A service with a 100A main breaker and then install a 100A breaker to a sub panel, there is no problem with putting any size breaker in a panel.
How many ground rods do I need?
If a single ground has a resistance of 25 ohms or less, building codes allow it to be used as the only grounding device. If the resistance of a ground rod is greater than 25 ohms, at least one additional ground rod is required.
Why do you not bond a sub panel?
So, why do you separate the ground and neutral in a subpanel? Because when we bond them together, it gives your neutral wire (the one carrying electrical currents BACK to the source) multiple pathways. That’s how the chassis of some equipment will become energized.
Can you feed a panel from the bottom?
