Answer: 100 amps
Mains electricity (Commonwealth English) also known by the American English terms utility power power grid domestic power and wall power or in some parts of Canada as hydro is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through electrical infrastructure in many parts of the world.
Thu Sep 08 2005 14:30:00 GMT-0400 (Eastern Daylight Time) · The service drop provides the building with two 120 V lines of opposite phase so 240 V can be obtained by connecting a load between the two 120 V conductors while 120 V loads are connected between either of the two 120 V lines and the neutral line. 240 V circuits are used for high-demand devices such as air conditioners water heaters clothes dryers ovens and boilers while 120 V …

This setup produces three different voltages: If the voltage between the center tap (neutral) and each of the top and bottom taps (phase and anti-phase) is 120 V (100%) the voltage across the phase and anti-phase lines is 240 V (200%) and the neutral to “high leg” voltage is ≈ 208 V (173%).
The appearance of this plug is sometimes confused with a NEMA 10 connector rated for 240 V but the NEMA TT-30 is a 120 V device. The hot and neutral blades are angled at 45° from vertical and 90° to each other unlike NEMA 10 devices (where the angles are 30° and 60° respectively) also the plug is slightly smaller than a NEMA 10 and larger than ordinary 5-15P plugs.
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances. It consists of one or more uninsulated electric…
