Are secondary wires that solely feed streetlights treated differently than other secondary wires in the midspan, or do you still need to maintain a 30″ clearance in the midspan from the streetlight service wires?

NESC Rule 238D allows a reduced clearance to drip loops feeding a streetlight or traffic signal. If the service originates at a different pole, then a clearance of 40” to communication cables at the poles and 30” to communication cables in the span must be maintained from the secondary (service) wire, even if it serves a streetlight or traffic signal.
