    CQD - 3/24/23

    Good morning and an advanced shout-out thank you for your efforts. NEC® article 300.8 - Installation of Conductors with Other Systems states: Raceways or cable trays containing electrical conductors shall not contain any pipe, tube, or equal for steam, water, air, gas, drainage, or any service other than electrical. If one were to install a cable tray divider, could the cable tray then share electrical conductors with any of the other systems mentioned keeping the conductors on one side of the divider and the other system on the opposite side? I'm thinking probably not but would appreciate another opinion. Thanks in advance, Greg Prudence
