Q1. A powerline technician supervising a site in Ontario sees a mobile crane working beside an energized 115 kV line. The nearest point of the boom is 2.5 metres from the conductor, and the crane crew are not qualified electrical workers. Under Ontario's construction regulation (O. Reg. 213/91), what minimum distance must the crane and its load keep from a conductor energized at more than 750 V and up to 150 kV?
Worked Explanation: Ontario's construction regulation requires the crane, its load and any part of the boom to stay at least 3 m from a conductor above 750 V and up to 150 kV (4.5 m above 150 kV to 250 kV, 6 m above 250 kV). At 2.5 m the crane is too close and must be moved back. Other provinces set their own distances, so check the rules where you work.
Q2. A crew near Lethbridge attaches a down guy to the upper section of a wood utility pole. Which standard attachment hardware and bolt arrangement transfers the full mechanical load without cutting into the wood fibres, since the guy will carry a large dead-end pull for years?
Worked Explanation: Guy attachments such as guy hooks or pole eye plates are secured by through-bolts with heavy curved square washers. A smooth radius or thimble supports the strand without sharp bends that would notch the wires, and the load spreads over the wood.
Q3. An underground-fed streetlight near Sherbrooke has a fused connector in the pole base. During a patrol after a storm, a trainee opens the handhole, sees a small fuse holder on the wire between the underground cable and the luminaire, and asks what the fused connector is for. What is its purpose?
Worked Explanation: A fused in-line connector in the base protects the luminaire wiring from faults and lets the technician open the circuit to that one light for maintenance. The fuse size is set by the utility standard for the luminaire.
