Electrical Wiring in the Home/wiring question


I have a question regarding the replacement wiring of a bathroom exhaust fan/light combo. The existing fan/light had a white, black and blue wire. They were wired as follows: white2white, black2black and blue2red. Replacement has the following black&white for the fan, black&white for the light and a red&white for a night light. I was not planning on using the night light. Therefore should I wire as follows:the 3 whites together, the 3 blacks together and the 2 reds together.Or not wire the night light at all and take one of the blacks to the red of the 3 way wire. Also all the grounds (green) would go to the bare ground wire of the existing house wire. Thanks 4 your help.


Tape or cap the white and red wires to the night light. Connect the remaining 2 white wires from the fan to the white wire from the cable. Connect the black wire for the fan to the black wire from the cable. Connect the black wire from the light to the red wire from the cable and your set.

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.
