Wires leaving panel box


Is there a rule that says all wires exiting the panel box must be directed in a specific direction? A lot of pictures of panel boxes show the mains at the bottom and all wires going upwards. If you have a panel box on the first floor, and you have an open ceiling in the basement /crawl space, could you add a new circuits (washer/dryer) with wires down from the panel box into basement, and along perimeter to a location, then up to a new laundry area?

I realize that breakers, wire gauge, staples, boxes, receptacles must all be done properly. This is just a question about direction of the wires exiting the panel box in a situation where there are finished walls and ceilings.

No, there is no rule. Run the wire through the crawl space if that is easiest for you.

I like to run conductors out the bottom to get a gravity assisted flow of electrons. It helps cut down on utility costs.

Haha but the current has to return "up hill" back to the panel. Just remember, if you tie a knot in your wire/cord it will stop the flow of electrcity. And likewise if you take the cover off a piece of equipment and turn it over you'll dump all the electrons out.

As important as the electrons are it is the smoke that makes all electronics work... To prove this just let the smoke out and see what happens!!!

Conductors can exit the panel through any knockout (and you can buy tools that let you make additional knockout size holes in appropriate locations elsewhere in the panel). The principle practical limitation is the allowable bend radius of the conductors, which is sometimes an issue with large conductors used to supply power to a panel or send it from one panel to another.
