doubled breakered?

[Karl Fields]

Is there any issues with a double breaker? From the service I feed a panel that has a 100 breaker. From that breaker the line goes 300' feet to another panel with another 100 amp breaker and from there 150' to the actual distribution panel.
Besides having an extra 100 amp breaker, there a problem doing it this way?

the breakering is not a problem, however voltage drop could well be.

Other than the distance issues, how could voltage be effected?

 

[Orionrising]

yeah the issues would be the 450 feet from the main panel, depending on draw and wire size, would cause voltage drop.

There are a bunch of online calculators for wire sing to minimize that.

Yes, I'm fine with the voltages at that distance, just concerned with the multiple breaker issue. Thanks

No issue with multiple breakers.

What size and type of wire do you have feeding and coming off of the 100A breakers?

Depending on the number of breakers in the distribution panel, as you call it, you may need a breaker as a disconnect in that panel. Having a second breaker in a panel with no other circuits might be useless other than a way to switch off the feed.

The voltage will only be affected when u put a load on it. If your load is small then the voltage drop might be acceptable.

Theres a simple formula that can be used to figure out what the voltage drop will be. As pattenp asked, what size and type of wire do u have between all these points?

Aside from what has already been mentioned concerning voltage drop, you will also need the appropriate grounding and bonding (such as ground rods, ufer, etc) done at each structure upon which these 100 amp breaker panels are attached.
