I have an extension cord that is 15ft and it is a 16/3. I have a 20ft of 12/2 cable. Can I use it to extend the extension cord for about 5 more feet?
The devices connected to the extension cord will still be a max of 13 amps. I just want to use the 12/2 so that I won't buy new cable.
I am thinking about cutting my extension cord (16/3) half way so that I can still use the end outlets-plug. If I can merge them, do I connect black and red from 16/3 to black on 12/2 and then black split to red and black again (see diagram)?
--red---- --red 16/3--- Flat Plug -- 10ft of 16/3 -- --12/2 black-- ----extension outlet --black-- --black 16/3--
neutrals and ground will be connected accordingly.
