Find the voltage(s) for the appliance shown on its “rating label”. It is on device’s body or on the power supply module that is part of a detachable power cord. The “rating label” usually has the manufacturer’s name, model number, and electrical specifications. Sometimes, it is molded into the body of the appliance.

“208-240” or “230” or a number close to these values "100-240” or numbers showing a large difference between the 2 values

If the label reads “208-240” or “230” or a number close to these values, followed by V or VAC or Volts, then you need a voltage converter.

“100-240” or numbers showing a large difference between the 2 values

No, you do not need a voltage converter!

If the label reads “100-240” or numbers showing a large difference between the 2 values, followed by V or VAC or Volts, AND your electricity voltage falls between the 2 numbers, you do not need a voltage converter. Your appliance was made to operate on power from many different countries. You may need to change the plug or use a plug adapter available from numerous web stores.

What kind of voltage converter is needed?

For this you need the “amperes” (A or amps) or the “watts” (W) from the appliance’s rating label. Sometimes “volt-amperes” (VA) is given. While not exactly the same as watts, one can use volt-amperes in place of watts for deciding the type of converter to choose.

Step Up Transformer

If the rating label shows less than 5 amperes or 1200 watts, a step-up transformer is usually recommended. These are available from numerous sources on the internet.

Quick 220^® System (15 A)

If the rating label shows 12 amperes or 2880 watts, or less, the Quick 220^® 15 ampere, A220-15D is recommended. Twelve amperes is a continuous use rating.
This system can be extended to draw 15 amperes or 3600 watts for up to 3 hours.
The Quick 220^® 15 ampere system will also accept a draw up to 50 amperes momentarily for the starting of motors, electronics, and similar items.

Quick 220^® System (20 A)

If the rating label shows 16 amperes or 3840 watts, or less, a Quick 220® 20 ampere, A220-20 is recommended. Sixteen amperes is a continuous use rating.
This system can be extended to draw 20 amperes or 4800 watts for up to 3 hours.
The Quick 220^® 20 ampere system will also accept a draw up to 50 amperes momentarily for the starting of motors, electronics, and similar items.

Electrician

As you approach the limits of the various converters above or if you do not have the 120 volt circuits available which will support them, we advise having new circuits installed.

Which 20 Ampere Quick 220^® System should I choose – A220-20D or A220-20L?

These items are identical except for the 208-240 volt outlet. Choose the model Quick 220® System based on the type of plug on your device.

The “D” version accepts straight blade 208-240V plugs commonly found on air conditioners, electronics, office equipment, and EV charge cables. These are technically known as NEMA 6-15 or NEMA 6-20 plugs.

The “L” version accepts twist-locking 208-240V plugs commonly found on maintenance equipment where there is pulling on the power cord. This is known as a NEMA L6-20 plug.

If you have a NEMA L6-30 plug AND the ampere demand of your appliance is less than 20 amperes, your appliance may be powered by the Quick 220^® A220-20L using the CORD109 adapter.
