How 2 Change Tandem Outlet 2 a Standard Plug Outlet

by Willy
(Canada)

Hi, Gary: - I have 2 outlets that are tandem blade receptacles 240V, 15A, that I need to change to 110V 15A. Rite now they are in a most convenient location that I need to change. I have no use rite now for tandem blade/240V receptacles. How can I change these to 110V-15A receptacles?
Can I just move these wires in the main breaker box to 110V connection, 15A breaker, & replace these tandem blade receptacles with standard 15A outlets?? Waiting 4 UR reply. Novice Electrician WILLY.

changing outlets from 240vac to 120vac
by: Gary

Willy,
You should have red, blk & wht wires going to outlets. Use black for hot, white for neutral and tape up both ends of red wire. Not to be used. In breaker box, connect the blk wire to single 15a circuit breaker. Wht wire connects to neutral bar. Be sure a ground is connected. Should already be connected. Look at my outlet page for connection to
Outlets. You should be good. Send pics if it helps.

Hope this helps.

Willy,

You are correct, you can change the power going out to the outlets by connecting one lead to the main buss (15a Breaker) and the other lead to ground (at the Main Breaker Box). This will get you your 115vac. You have 2 main busses in your breaker box, If you put a meter across the 2 you will see 240 Vac on your meter. If you put a meter on 1 buss to ground (or Neutral), you will see 115 Vac on your meter. Neutral is the same as ground as far as the US goes..To the best of my knowledge, I believe Canada has the same electrical sources as the US.

As you mentioned, you will have to replace your outlets to a 115Vac version of receptacles. Your extra lead at the outlet will not be used. Be sure to properly tape the ends and that all grounds are safely attached.

Thanks for visiting. Hope this helps.
