U.S. code adoption
Mississippi — energy & appliance code adoption
No. This page summarizes electrical (NEC), appliance-listing (UL 858), fire-code, and energy-storage (UL 9540 / NFPA 855) code adoption for Mississippi, with primary sources.
Is UL 858 required in Mississippi?
No. No code currently in effect in Mississippi requires UL 858 listing for household electric ranges. Without a statewide electrical code referencing 'listed' appliances, UL858 is not legally required at the state level. Individual municipalities (Jackson, Hattiesburg, etc.) adopt NEC locally and DO require listing.
Are NRTL-listed (UL / ETL / CSA) appliances required in Mississippi?
Mississippi has no statewide electrical code, so listing requirements are set by local AHJs. Mississippi historically has had no statewide residential electrical code. Adoption is at the city/county level. Many populated jurisdictions adopt a recent NEC, but rural unincorporated areas may have minimal-to-no enforcement.
Which edition of the NEC does Mississippi use?
Mississippi has no statewide NEC adoption; the applicable edition of the National Electrical Code is set by local authorities having jurisdiction (AHJs).
Is UL 9540 required for residential energy storage in Mississippi?
Not yet determined for Mississippi. Mississippi has no statewide fire code for residential. The Office of State Fire Marshal (under MID) references NFPA standards for state-owned buildings only — municipalities adopt independently.
Is UL 9540A fire-propagation testing required in Mississippi?
Not yet determined for Mississippi.
What is the residential energy-storage capacity limit in Mississippi?
Mississippi has no jurisdiction-specific residential energy-storage capacity cap beyond the model-code default (typically 20 kWh per dwelling unit under IFC §1207 / NFPA 855).
Which fire code does Mississippi enforce?
Mississippi enforces other. State Fire Marshal references NFPA standards for state buildings; residential is local.
