Electrical Question from Marcello about 220 Volt Wiring Conversion
Background: Marcello, a Homeowner from NY, NY
Question: I have an outlet that is rated for 250v and 30 amps, which is being used for and A/C. I recently purchase a new A/C. The new one requires a 220v and 15 amp rated outlet. Do I have to change what I have or can it be used safely as it is currently?
Thanks for your electrical question Marcello. The existing circuit can be converted from 30 amps 250volt to 15 amps 220volts (the range ofÂ 220 to 240 volts is typical). A new 2-pole or 15 amp 240volt circuit breaker will need to replace the existing 30 amp circuit breaker. At the outlet location the existing 30 amp 250 volt outlet will need to be replaced with the specified 15 amp 220 volt outlet to match the cord of the new air conditioner unit. If the #10 wires are too big for the new 15 amp outlet then splice #14 wires to the #10 wires to be used for the connection to the 15 amp outlet.
