    Default Water supply pipes over service panel

    Galvanized water supply pipes or routed over service equipment and have leaked or dripped condensation. I know that routing supply pipes over service equipment is not allowed, however I am not sure on what code allows. Just looking for a little more clarification.

    Is there a specification for minimum width?

    Noticed that in your original reply. What I was asking was is there a minimum for the "panel board" or does the sliding space enter into the allowance for pipe clearance?.

    This differs from the NEC. The minimum width is 30 inches, which does not need to be centered on the panel. The panel can occur anywhere in that width. The door does need to be able to open 90 degrees.

    Exception: Control equipment that by its very nature or because of other rules of the Code must be adjacent to or within sight of its operating machinery shall be permitted in those locations.
    - - (1) Indoor. Indoor installations shall comply with 110.26(F)(1)(a) through (F)(1)(d).
    - - - (a) Dedicated Electrical Space. The space equal to the width and depth of the equipment and extending from the floor to a height of 1.8 m (6 ft) above the equipment or to the structural ceiling, whichever is lower, shall be dedicated to the electrical installation. No piping, ducts, leak protection apparatus, or other equipment foreign to the electrical installation shall be located in this zone.
    - - - - Exception: Suspended ceilings with removable panels shall be permitted within the 1.8-m (6-ft) zone.
    - - - (b) Foreign Systems. The area above the dedicated space required by 110.26(F)(1)(a) shall be permitted to contain foreign systems, provided protection is installed to avoid damage to the electrical equipment from condensation, leaks, or breaks in such foreign systems.
    - - - (c) Sprinkler Protection. Sprinkler protection shall be permitted for the dedicated space where the piping complies with this section.
    - - - (d) Suspended Ceilings. A dropped, suspended, or similar ceiling that does not add strength to the building structure shall not be considered a structural ceiling.

    Not different in the NEC.
