TxDOT
ASC designs and builds roadway illumination panels for TxDOT and NTTA. We build either of the following electrical service types.
Standard Electrical Service Types
Service Type | Description | Notes |
---|---|---|
Type A or C | 480 volts, 3-wire with center ground | Three-wire branch circuits consisting of two line conductors and a ground. |
Type T | 120/240 volts, 3-wire with center ground (main lug only — no main breaker) | Used for traffic signals, traffic management systems, and irrigation systems. Not typically used for illumination (except at lighted intersections with traffic signals). |
Type D | 120/240 volts, 3-wire with center ground (main breaker) | Used for traffic signals, traffic management systems, and irrigation systems. Not typically used for illumination (except at lighted intersections with traffic signals). |
