A dedicated circuit has its own breaker in the electrical panel. Large-draw appliances like air conditioners, refrigerators, space heaters and washing machines all require a dedicated circuit because they are heavy power users.
Just so, do I need a dedicated circuit for microwave?
The microwave oven needs a dedicated 20-amp, 120/125-volt circuit to feed it. This will require 12/2 NM wire with a ground. Although it's not uncommon to see microwave ovens plugged into standard appliance outlets, larger microwave ovens can draw as much as 1500 watts, and these need their own dedicated circuits.
How many outlets can be on a 20 amp circuit?
I'm ask so many times how many outlets and or lights can I put on a 15 amp or 20 amp breaker. Well NEC code does not have it listed that way. By rule of thumb you would stick with 8 to 10 outlets and or lights per breaker. Now this is of course they are 120 volts 60mhz (USA or Canada).
Can you plug a microwave into a regular outlet?
The microwave should be plugged into its own properly grounded, dedicated electrical outlet to prevent the flickering of the lights, blowing of a fuse or tripping of a circuit breaker. The microwave cord is three to five feet long (depending on model). The extension cords are usually marked 15 or 20 amps.
