How many junction boxes can you have in a house?
There are no limits on the number of junction boxes (without devices) in any particular circuit. Each piece of ‘utilization equipment’ reduces the maximum allowable load by it nameplate rating, 180va for each receptacle, and each light fixture at its maximum labeled lamp wattage.
Can I put a junction box in a wall?
Junction boxes must be installed where they are always accessible; never install a junction box in a concealed wall or ceiling space where the box cannot be accessed in the future. Junction boxes also must be covered with solid covers with no holes.
