Repeated grounding means that in a system where the neutral point is directly grounded, a metal wire is used to connect the grounding device at one or more places on the neutral main line. Attach a second grounding wire from the mounting. Abstract - The most common medium voltage electric dis-tribution system in the United States is multigrounded wye using a common neutral for both primary and secondary systems. The effective interconnection of the multi-grounded wye neutral conductor with the earth ground ref-erence is very. A sub panel is a secondary distribution point that receives power from the main service panel, allowing for the extension of electrical service to a remote area of a building or a separate structure like a garage or shed. It looks like two lines, and in fact they are all together.
