Microwave Oven Lost Power
Electrical Question: We have several microwaves in our snack shop and if we plug three or more into an electrical strip because of lack of wall plugs they tend to short out or just lose power.
- Would a surge protector benefit better or what do you recommend?
This electrical wiring question came from: Steven, a Teacher in Texas.
Thanks for your electrical wiring question Steven
Planning A Microwave Oven Circuit
Skill Level: Intermediate to Advanced – Best performed by a licensed electrician.
Tools Required: Basic Electricians Pouch Hand Tools, electric drill, auger bits and extension cord.
Estimated Time: Depends on personal level experience, ability to work with tools and install electrical circuit wiring.
Notice: Installing additional outlet wiring should be done with a permit and be inspected.
How to Wire an Electrical Circuit for a Microwave Oven
- Microwave ovens generally require a dedicated circuit, so if you are trying to run several off of the same circuit then naturally the circuit will not support the load. So basically, you are over loading the circuit. In a case such as this a surge protector will not help, however what will help is to install an additional circuit or two.
- Basic circuit planning requires you to add up all of the required watts or amps and determine how many circuits will be required. Conventional microwave ovens are 120 volts, so installing 20 amp circuits would be best, you just need to determine how many more are required.
- Depending on the exact size or electrical load of each microwave oven, you may find that you can have more than one microwave oven on a single circuit breaker.

Ohms Law Formula for Microwave Ovens
- The Ohm’s Law Calculations for Electrical
- Using the Ohm’s Law is a way to determine information needed to understand how to design electrical circuits.
- This formula works with three main variables and depending on what is known can produce a missing factor which is needed to determine the circuit size.
- The Ohm’s Law is also used when designing appliances and building electrical equipment and devices.
