Connect First Hot Wire

What happens here

The electrician proceeds to connect the first hot wire. He uses an electrical connector, commonly referred to as a 'bug,' which already has some tape on it, indicating the wire may have been previously damaged or required initial insulation. He inserts the service wire fully into the connector. He then uses an Allen wrench to securely tighten the connector onto the wire. He reiterates the safety principle that as long as he avoids creating a 'current loop' (allowing electricity to flow through himself) and holds onto the insulated parts, he is safe.

Goal: Securely connect the first live wire to the overhead service line.
