Plug fridge and micro in same outlet?

Hi, I am need some quick advice as my new cabinets go in. My cabinet maker is on a roll. We think there is room above the cabinets or fridge for a small microwave. The fridge is plugged into an outlet behind it and I would like to plug the microwave into the same outlet. What do you all think? My trailer is a 1974 if that matters. Pam

What matters more is your type of refrigerator. As long as it is an RV fridge, and not a replacement "dorm fridge", you should be able to run both a small microwave & RV fridge from the same outlet.

If the circuit breaker should trip, then either unplug the fridge when the microwave is needed or run a new power wire for the microwave.

I certainly agree with Tom on this.

Pam I am sure hope that you are taking lots progress of shots of your renovation. I for one would love to see how you're doing. Any chance that you might treat us to a few photos?

Pam,

You didn't post any specifications but I'll assume that the supply circuit is 15 amp. Given that, your RV fridge running on electric will draw 350-450 watts, depending on which element it is using. A small microwave generally uses 800-1000 watts so you have a total max of 1450 watts.

At 120 volts, a 15 amp circuit delivers 1600 watts, so you should be fine! (P=IE) or watts=volts X amps from Ohm's Law.

You guys are great!

Lew, it seems like I need to understand more! ((P=IE) or watts=volts X amps from Ohm's Law)! One of the first things I will do in my new lounge in the AS is study electricity!

Meanwhile I will attempt some pictures... First I have to go and make them smaller so they will upload. Pam

My Project

Okay, here are a couple of pictures in progress. I realized as I looked that I have been taking lots of close up pictures of water pipes and wiring etc. so I will remember what is behind and under all my new cabinetry. Here are a couple of the most recent pix I have. We are using birch and birch ply. I haven't seen the progress in the last week, so I will get more pictures mid week... Pam

Hi Pam,

I see that you are just down the road from me. I am in Beaverton. Your cabinet work is looking nice from what I can see in your photos. I belive you mentioned earlier that you were having the cabinet work done? Do you mind sharing who is doing the work?

Thanks,

Malcolm

Pam,
I would be cautious. If you turn on the microwave and the refrigerator starts( it takes more amperage while starting) it will probably trip the breaker, especially an old one. If you run a new circuit you'll never have a problem.
From your photos now would be the time to add a circuit.
I hope this helps you,
Mike

Mike,

If I read your post correctly, you are saying that the refer has a start-up draw, which is incorrect. A household refer with a compressor will have an extra draw on start-up, but an RV fridge uses a heating element and has no initial draw other than the rated watts of the element.

Perhaps you were referring to the micro?

I "second" Lew's sentiment. If you really want to get technical, heating elements do have a start-up surge but it is nowhere near as intense as a compressor-driven refrigerator.

As long as Pam has a refrigerator designed for RVs then Lew's observation is valid.

Malcolm, A very good friend of mine is doing the cabinets. He is retired and 'winters' in Oregon (?!) from Minnesota. I have been trying to talk him into this for 2 years and he begrudgingly agreed. We have my trailer at another friends house in Philomath and he is using his workshop. I was down there today to finalize some of the plans for drawers vs pull out pantries etc and I forgot to get pictures. Arh! I am having withdrawals ready. And BTW, he is doing a great job and things are looking very good.

Anyway I don't think he will be talked into this again anytime soon, but you never know. Maybe he will be hooked now! I am in Lake Grove, so very close to you. I would love for you to see the finished product when I finally get her home. Keep in touch. Pam

Thank you all for the informative discussion... it has been very helpful. As always you are great and generous with your knowledge. Maybe someday soon I will be able to answer some questions for others. Pam

I'll stand corrected on the RV refrigerator. I had to explain this to many past customers, I answered out of habit. But I got a chance to learn something, thank you for correcting me.
Mike
