Subpanel Daisy-Chain

How many subpanels can you install to one another? This Master Electrical Inspector has the answer.

Question: Can a subpanel take power supplied from a circuit breaker into another subpanel? In other words, tin y'all daisy-chain subpanels?

Answer: Yes.

The chief electric service panel is where co-operative circuits originate. A branch circuit consists of the circuit conductors betwixt the final over-electric current device protecting the circuit and the lights, receptacles and equipment supplied by the branch circuit.

In that location are three main types of branch circuits:

1. General-purpose co-operative circuits for illumination and other general purposes
2. Appliance branch circuits that supply ability in the kitchen for countertop receptacles, such equally small appliances
3. Individual branch circuits that only supply one utilization equipment, such as a central heating gas furnace, an electric clothes dryer, an electric range and then on.

The main service panel likewise may contain fuses or circuit breakers that supply "feeder" conductors to downstream subpanels. A feeder consists of the circuit conductors that originate at the chief service console and are routed to the subpanel, in which there are branch circuit over-current devices for the downstream branch circuits.

You could daisy-concatenation a feeder from the principal service panel (Console A) to a subpanel (Panel B), and and then run another feeder from Panel B to another subpanel (Panel C). In that location really is no limitation to this concept, as long as every set of feeder and branch circuit conductors are properly sized and rated in amperes, and each feeder and co-operative excursion has the proper over-current protection (fuse or circuit breaker).

Always check with your local electrical inspector nearly the specific code requirements in your area.
