A 240/120 V split-phase service drop providing power to a residence in USA. The three wires from the utility pole enter through a weatherhead (top) into a vertical conduit, which routes them to the electric meter (bottom). From there they pass through the wall of the house to the electric panel and Main Fuses or Circuit Breakers inside.
A service drop carries this lower voltage to the customer's premises. Subtransmission lines carry higher voltage power from regional substations to local substations. They usually carry 46 kV, 69 kV, or 115 kV for distances up to 60 mi (100 km). 230 kV lines are often supported on H-shaped towers made with two or three poles.
Closer to the customer, a distribution transformer steps the primary distribution power down to a low-voltage secondary circuit, usually 120/240 V in the US for residential customers. The power comes to the customer via a service drop and an electricity meter. The final circuit in an urban system may be less than 15 metres (50 ft) but may be ...
In 1912 the first 110 kV-overhead power line entered service followed by the first 220 kV-overhead power line in 1923. In the 1920s RWE AG built the first overhead line for this voltage and in 1926 built a Rhine crossing with the pylons of Voerde , two masts 138 meters high.
A weatherhead on a residence in Mount Vernon, Washington, US. A weatherhead, also called a weathercap, service head, service entrance cap, or gooseneck (slang) is a weatherproof service drop entry point where overhead power or telephone wires enter a building, or where wires transition between overhead and underground cables.
The inside of an attic is visible at the scene where a row of townhouses was damaged after a box truck was caught on wires and pulled off part of the roof on Randolph Court, Thursday, Aug. 22 ...
The other end of the three secondary windings and the neutral are brought down the service drop to the service panel. 230 V loads are connected between any of the three-phase wires and the neutral. Because the phases are 120 degrees from each other, the voltage between any two phases is sqrt(3) * 230V = 400V, compared to the 2 * 120V = 240V in ...
GOP Rep. Byron Donalds, a top Trump ally in Congress, seems more vocal about running for Florida governor in 2026 in the race to succeed term-limited Republican Gov. Ron DeSantis.
