Section 250.25 is brand new for the 2020 Code cycle. It has been created to establish grounding and bonding rules for add-on disconnects, such as a PV system disconnect acting as that PV system’s service equipment, when the disconnect is attached to conductors on the supply side (meaning before the main cut-off) of the utility service disconnect. Section 230.82 provides electricians with a list of equipment/systems that can legally connect to the conductors on the supply side of an electrical system serving a home or business. The new Section 250.25 outlines grounding and bonding rules for a disconnect serving just such an add-on system.

The demand for quick, easily changeable lighting fixtures has led to the development of products consisting of an electrical receptacle with a locking device capable of supporting the luminaire weight. That receptacle also makes and breaks the electrical contacts responsible for feeding the luminaire. The load-bearing portion of this new component, called the mounting support, is installed in the ceiling box and includes the energized receptacle contacts that will feed the lighting fixture or ceiling fan. An attachment fitting that connects to the mounting support and the energized contacts built into that support is incorporated into the design of the lighting fixture or fan. The fixture or fan attaches to the mounting support with a twist lock motion. These new attachment fittings can save valuable time when installing lighting outlets.
