ABSTRACT:
A neutral connection arrangement for use with a pair of aligned transfer switch assemblies of an electrical panel. The first transfer switch assembly is operable to regulate electrical connection of a neutral conductor of a utility service, and the second transfer switch assembly is operable to connect a neutral conductor of a generator. The neutral connection arrangement may be in the form of a neutral bracket apparatus that includes a bracket having a first mount member, a second mount member, and a third mount member. The first mount member is attached at the first neutral bus of the electrical panel, and the second mount member is attached at the second neutral bus of the electrical panel located opposite the first neutral bus. An elongated body portion electrically connects the first and second mount members. The third mount member is generally U-shaped and extends from the elongated body portion for electrical connection to the first and second transfer switch assemblies. Alternatively, the neutral bracket apparatus may have an outer end secured to one of the neutral buses of the panel, and an inner end that is supported at the center of the panel by an insulating block. The neutral bracket has an inner connection member at the inner end, which is engaged by the switches. In another version, the neutral connection may be made via a neutral terminal secured to an insulating block. The terminal is engaged with an inner connection member, which in turn is engaged by the switches.
