Loadcentre Spaces vs Circuits
Loadcentre Spaces vs Circuits reference with assumptions and boundary notes.
Reference boundary
Panel label reference only. It does not approve tandem breakers, circuit count, panel loading, or breaker compatibility.
Reference table
Decode common loadcentre spaces/circuits labels such as 30/60 or 40/80.
| Panel label | Spaces | Max circuits label | Label meaning | Boundary |
|---|---|---|---|---|
| 12/24 | 12 | 24 | 12 full-size spaces and up to 24 labelled circuits where product markings permit | label reference only; tandem breaker use depends on panel and breaker markings |
| 24/48 | 24 | 48 | 24 full-size spaces and up to 48 labelled circuits where product markings permit | label reference only; tandem breaker use depends on panel and breaker markings |
| 30/60 | 30 | 60 | 30 full-size spaces and up to 60 labelled circuits where product markings permit | label reference only; tandem breaker use depends on panel and breaker markings |
| 40/80 | 40 | 80 | 40 full-size spaces and up to 80 labelled circuits where product markings permit | label reference only; tandem breaker use depends on panel and breaker markings |
| 42/84 | 42 | 84 | 42 full-size spaces and up to 84 labelled circuits where product markings permit | label reference only; tandem breaker use depends on panel and breaker markings |
