What gauge wire to use for a sub panel?
That would depend upon how many amps will be used in the sub-panel. For example, a 30-A subpanel would need a minimum of 10 AWG feeder conductors.
What is difference between to busbar and feeder?
The busbar is used as a conductor and is used as a connection between the parallel and the feeder. The feeder is the supply, and it handles the relays.
WHAT is FCBC with DVR on dg electrical panel?
FCBC stands for "Feeder Circuit Breaker Control," which is a system used in electrical panels to manage and protect feeder circuits. DVR refers to "Dynamic Voltage Regulation," a technology that helps maintain a consistent voltage level despite fluctuations in supply or demand. In a DG (Distributed Generation) electrical panel, FCBC with DVR ensures that the feeder circuits operate efficiently and safely, providing better voltage stability and improving overall system reliability. This combination is particularly beneficial in systems that integrate renewable energy sources or other distributed generation technologies.
What size generator for 200 amp service?
Usually generators are not sized for the entire house load. At 200 Amps and 240 volts that would be a 48 KW generator. You can get by with less by just creating a transfer electric panel with critical circuits. You can probably get by with a 20 KW generator.
Can you put a 60amp breaker and a 50amp breaker on a 60amp subpanel just as long as they are not being used at the same time?
You can. Using these size breakers in a 60 amp sub panel might be pushing the limit for breaking the sub panels feeder breaker. The breaker feeding the sub panel will have to be no bigger than 60 amps because of the main bus bar capacity of the sub panel. It would be better to install a 100 amp sub panel and then there would be a bit of a buffer and you will have the ability to add additional small load circuits.
