SEU (Service Entrance cable, Style U) is designed for carrying power from the utility connection point to the main electrical panel. Its sunlight-resistant jacket allows for safe use in above-ground, outdoor exposed runs — a requirement most standard NM-B cable does not meet. The 6-6-6 configuration provides two 75A-rated hot conductors plus a bare concentric ground, making it a solid choice for residential service entrances and sub-panel feeds.
