Final answer:
The correct size range for compression tool type connectors used with aluminum and ACSR conductors is #6 to #10. High-voltage wires seen on towers are not insulated, which makes the true or false statement false. Wires are sold in gauges, representing different diameters and current-carrying capacities, with common household wiring ranging from #10 to #14 gauge.
Step-by-step explanation:
The size range for compression tool type, self-insulating, and bare connectors used for splicing stranded conductor range for aluminum and ACSR which are typically used for secondary and service applications is from #6 to #10. This range is suitable for the common sizes that are utilized in these types of electrical installations.
In reference to the true or false question provided, the statement is false. High-voltage wires, the ones connected to tall metal-frame towers, are often bare and do not have an insulating material wrapped around them. They are held aloft by insulators to prevent current from flowing to the ground but are not insulated themselves.
Wire gauge is an important concept in electrical engineering and is based on the American Wire Gauge (AWG) system. Wire gauge indicates the physical size of the wire, which in turn determines its current-carrying capacity. Larger gauge numbers indicate thinner wires, whereas smaller numbers indicate thicker wires which can carry more current. In household wiring, common wire gauges range from #10 (2.588-mm diameter) to #14 (1.628-mm diameter).
