Can I pull 120 from 240?

Hi, I am building a new home and need to install an invisible fence for dogs. I would like to place the control unit in the crawlspace right next to a junction box that houses a 4 wire 240v splice for my range. Can I pull 120v from this box? If so will there be any issues when both units are running? Hope someone can help. Thanks.

Only if you want to burn your house down. You need a GFCI protected 120v receptacle. It is against code to have a breaker of more then 20 amps on a 120v general purpose circuit. The 40 or 50a breaker on the stove circuit can not protect fixtures and wiring that would melt and burn long before they tripped the breaker.

Not safely or in compliance with code.

You could possibly extend a different circuit in the vicinity as long as it does not serve the kitchen, dining, bathroom, or laundry areas. Another option is to install a new circuit from the panel to the control box. In either case, make sure the receptacle in the crawlspace has GFCI protection.
