Electrical Wiring in the Home/Can I use a dehumidifier in my condo with Cu/Al wiring?


Can I use a dehumidifier in my condo that has a notice in the user's manual that says "Notice Aluminum house wiring may pose special problems" .  The wiring on my circuit breaker says Cu/Al 60/75deg C Wire while the circuit breaker is rated for 20 amps. In the owner's manual it says use wall receptacle of 3 wire grounding rated at 15A, 125V AC. Power supply - Use 15Amp circuit breaker.  I looked at my receptacle and it is 3 prong grounded so I guess I'm OK?  My Condo was built in 2005 in Florida (Palm Coast.  By the way I'm originally from Bayonne NJ. Say hello to NJ for me!  Thanks for your consideration.


Your fine and you absolutely can use that dehumidifier with no worries. Your using a 20 amp circuit which is better than 15 so your above minimum. BTW they stopped using aluminum wiring in houses a long time ago.

My daughter lives near by in Jersey City not far from Liberty State park, so we send a warm NJ hello back to you Charles !

Best regards

Licensed contractor in Closter New Jersey.

"The Frank Williams School of Electrical Construction". My dear old boss is 100 ! and still going God Bless him. I started working for "Tenafly Electric" right out of high school at 19. He was tough but I learned more working for him in 8 and half years than most guys. We did mostly industrial work while doing some commercial and residential so I was fortunate to be exposed to all 3 areas of electrical construction. The guys I worked with were all good guys and I stay in touch with some of them still. Most of us went into our own buisness's which says something about the caliber of the guys I worked with. We had some interesting clients : Wella Corp. of shampoo fame, Farah Fawcett etc, I didn't buy shampoo for 10 years. It was a great place to work. Pan Am the former airline just before they went under, another great place to work, nice clean environment. C&C Metals, the largest button manufacturer in the US at that time, a not so clean environment but a very interesting place to work, lots of machine's cranking out buttons of all kinds but you had to be on your toes, it was a potentially dangerous place to be . All kinds of action going on around you.
