How electrical and panel upgrade costs vary in South Dakota
State-specific code or insurance rule: South Dakota's State Electrical Commission is one of the smallest state agencies in the country (under 30 inspectors statewide) — the Commission directly inspects every state-jurisdictional installation, with no county-level inspection programs, and the Class B Master credential is restricted to single-family residential up to 200A service while Class A authorizes any voltage and any service size.
