Electricityin general can be a confusing and intimidating subject. One very common point of confusion is the difference between 120V and 240V, and how to determine what voltage type to use for various situations. In this article we’ll cover these basic differen.
Itis more than sufficient to run any residential pump on 230-240V. Your timer obviously has a clock currently on 110V. Your timer contactor contacts are rated for 220V, but you will need an extra wire for the second phase to the clock and than to the motor, since the second wire to the motor is white which is against the code.
230vand 240v hot tubs are similar to 220v hot tubs but require slightly more electrical power to operate. 230v and 240v hot tubs are less common than 110v and 220v hot tubs, but they offer the sameVtĂ© dobÄ› se v EvropÄ› pouĹľĂvalo pĹ™evážnÄ› napÄ›tĂ 220/380 V. Ve VelkĂ© Británii a v zemĂch, kterĂ© tehdy patĹ™ily pod jejĂ správu – Kypr, Malta, Gibraltar, se pouĹľĂvalo napÄ›tĂ 240/415 V. V Norsku se provozovalo napÄ›tĂ 230/400 V. Po dvacetiletĂ©m jednánĂ se podaĹ™ilo dosáhnout sjednocenĂ na hodnotu 230/400 V.
Theaverage 220/ 240 V appliances utilize 3 wires : . A hot wire: Carries the current to the fixture. Another hot wire: Also carries the current to the fixture. A copper wire: Ensure user safety. There is no neutral wire here but when one of the hot wire is positive, the other is negative. That arrangement complete the circuit.
Mostresidential voltages are either 110-120 Volts or are 240 volts. However, you’ll find 115, 127 and 220, or 230 Voltages and some others not used as often. Highest Three-Phase Voltages. 480 Volts on the 60 Hz frequency is the highest three-phase industrial voltage. Puerto Rico, the U.S. Ecuador, Costa Rica, El Salvador, and Honduras have them.Thetable shows that in most countries the mains supply is between 220 and 240 volts (50 or 60 Hz); countries that operate on 100-127 volts are greatly outnumbered. The list also reveals that types A and C are the most frequently used electric plugs worldwide. If you take a scroll down the page, you will notice that most countries have a
220” and “240” are the same thing. “220” is what the unqualified use to describe 240 volt circuits. 208 can only be obtained from a 3-phase wye system. 240
