Are overhead service conductors permitted to be accessible for services over 600V nominal?

Overhead service conductors that operate at voltages exceeding 600 volts nominal are generally not permitted to be accessible. Accessibility in this context means that the conductors should not be easily reachable by the general public or could pose a safety hazard if someone were to come into contact with them. This is rooted in safety regulations designed to minimize the risks of electrical shock or injury.

For conductors over this voltage threshold, specific safety guidelines and codes dictate that they must be installed in a manner that protects both the equipment and individuals in proximity. These regulations often require that such conductors be elevated to a height or installed in a way that reduces the likelihood of accidental contact.

The other options about special permissions or jurisdictional variations may introduce some complexity, but in general, the fundamental safety principle is that service conductors over 600 volts must be installed to prevent unauthorized access and potential hazards.
