Washing machine power supply requirements:
*Rated Voltage: Typically 220-240V AC (VAC)
*Rated frequency: typically 50Hz
*Wattage Rating: Varies by model, but typically 1000 to 2000 W
*Current Type: Alternating Current (AC)
* Safety socket: three-prong grounded socket (ground, neutral, live)
* Wiring: Copper wire of appropriate size (see below)
* Overload protection: circuit breaker or circuit breaker of appropriate rating (see below)
Calculation of wiring size and overload protection rating:
* Determine the power rating of the washing machine in watts (W).
*Divide the power rating by the voltage rating to get the current rating in amperes (A):
“`
Rated Current (A) = Rated Power (W) / Rated Voltage (V)
“`
* Select a wire of sufficient size to carry the rated current. For copper wires, the cross-section can be calculated using the formula:
“`
Wire size (mm?) = Rated current (A) / 8
“`
* Select a switch or circuit breaker rated equal to or greater than the current rating.
Example:
For a washing machine with a rated power of 1500 W and a rated voltage of 220 VAC:
*Rated current = 1500 W / 220 V = 6.82 A
* Wire cross-section = 6.82 A / 8 = 0.853 mm? (is it recommended to use 1mm wire?)
*Overload protection rating = 10A (nearby breaker or circuit breaker rating)
Connecting the washing machine:
1. Turn off the main power switch.
2. Plug your washing machine into a grounded, three-prong outlet.
3. Turn on the main power switch.
4. Plug the washing machine’s power cord into a power outlet and turn it on.
Security measures:
* Always turn off the power before performing maintenance on your washing machine.
* Make sure the outlet is properly grounded.
* Never use a damaged power cord or plug.
* Do not overload the washing machine with laundry.
*Keep children and pets away from the washing machine while it is running.
