Hello,

in my home are a few 240v outlets that used to serve air conditioners.
We now have a central air system, so those outlets are no longer
needed.

Can i leave the 240v outlets as is and plug any old device into them?
For instance, if i were to plug my alarm clock into that outlet, what
would happen?

How can iconvert them to 120v outlets? is it simply a matter of using
only one of the two hot wires to wire a new 15 or 20 am outlet?

thanks much
