I am connecting a new Hampton Bay ceiling fan to a 3-way electrical circuit (2 black and 2 white service leads to the fan). Instructions say to connect both the blue and black leads from the fan to the black power source. Since I have two black power leads, I tried putting the blue on one and the black on the other; no luck. If the two black power leads touch each other, the breaker blows. What am I missing? Thanks.
