Arc Flash Parameters: panelboard
IEEE 1584-2018 arc flash calculation parameters by equipment class and voltage class. Includes electrode gap (mm), working distance (inches), enclosure dimensions, and electrode configuration for switchgear, MCC, panelboard, and cable junction equipment.
| equipment class | voltage class | electrode config | enclosure depth mm (mm) | enclosure height mm (mm) | enclosure width mm (mm) | gap mm (mm) | insulation level pct (%) | notes | working distance in (in) | working distance mm (mm) |
|---|---|---|---|---|---|---|---|---|---|---|
| panelboard | 15KV | VCB | 508 | 914 | 762 | 152 | 100 | 15kV distribution panelboard / metering panel; IEEE 1584-2018 lacks a dedicated MV panelboard class — MV switchgear parameters applied per standard guidance; enclosure dimensions AI-estimated from typical MV panel | 36 | 914 |
| panelboard | 208V | HCB | 203 | 356 | 305 | 25 | 100 | Shallow LV panelboard at 208V | 18 | 457 |
