Switchgear pricing depends on several factors including amperage rating (400A–4000A), voltage configuration, NEMA enclosure type (NEMA 1 indoor or NEMA 3R outdoor), required certifications, and whether the unit must be built to utility-specific specifications. Custom configurations and larger ampacity units typically require a direct quote from a specialist.
