What is a jumper wire on a water meter?

A jumper wire is used to electrically bond the water distribution pipes throughout the house. Part of the reason that the water distribution piping in the home gets bonded is to make sure the pipes can’t accidentally become energized.

Does the grounding electrode conductor need to be continuous?

It is typically required that the grounding electrode conductor (GEC) should be one continuous length without a splice. But there there may become a time that it amay require a splice such as when work is done during remodeling or the replacement of existing electrical equipment.

Where a metal underground water pipe is used as a grounding electrode the continuity?

The GEC connection must be within the first 5 feet and the metal water pipe must be electrically continuous with a metal underground water pipe electrode. C: Interior metal water piping located 20 feet from the point of entrance to the building may be used as a grounding electrode conductor.

What shall the continuity of the grounding path or bonding connection to interior piping not rely on?

Continuity of the grounding path or the bonding connection to interior piping shall not rely on water meters or filtering devices and similar equipment. A metal underground water pipe shall be supplemented by an additional electrode of a type specified in Section 250-81 or in Section 250-83.

What is a jumper in plumbing?

The use of a temporary jumper permits testing of the building piping system for leaks and pressure loss and facilitates pipe flushing prior to the installation of the water pressure reducing valve. On unsecured jobsites, the jumper kit reduces loss from theft or vandalism.

How do you jump a meter box?

Quote from the video:
Quote from Youtube video: Or a pair of jumper bars. They go across where the socket went in. And then you're going to cover it to keep fingers out using a meter ring to hold the cover in. Place. These are called meter jumpers.

What is the purpose of the grounding electrode conductor?

Having established that the general purpose of the grounding electrode system is to provide a path to ground for high-voltage surge currents and lightning strikes, keeping the grounding electrode conductor outside the building would be common sense.

What is the general requirement in electrode grounding system?

Conductor is to be sized to carry maximum earth fault current of system at point of application with final conductor temperature not exceeding 160 deg. C (320 deg. F) for at least 5 seconds. Main earthing conductors are to be minimum 120 mm2 or as otherwise required by the particular Section of the Specification.

What is a system bonding jumper?

For clarification purposes, a system bonding jumper is a conductor, screw, or strap that bonds the metal parts of a separately derived system to a system neutral point [250.2].

What is the purpose of grounding the main bonding jumper?

For our typical AC electrical system, the purpose of the “Main Bonding Jumper” is to connect the equipment grounding conductors (E.G.C.) contained in each branch-circuit and the metal (conductive) service-disconnect enclosure to the Neutral Conductor of the electrical service.

Is a grounding electrode conductor ever permitted to be smaller than the main bonding jumper?

(D) Size. The main and system bonding jumpers must not be smaller than the sizes shown in Table 250.66, based on the area of the largest ungrounded conductor.

What two sets of conductors are connected by the main bonding jumper and where is this jumper located?

There are many different bonding jumpers installed in an electrical system, but there is only one main bonding jumper, and it is located at the electrical service. It is defined in Article 100 as the connection between the grounded circuit conductor and the equipment grounding conductor at the service.

What is the bonding jumper connection to a metal water pipe installed in a building required to be?

The bonding jumper(s) shall be sized in accordance with 250.66, based on the size of the feeder or branch circuit conductors that supply the building. The bonding jumper shall not be required to be larger than the largest ungrounded feeder or branch circuit conductor supplying the building.

Where do bonding jumpers need to be installed?

Bonding jumper supply-side is a conductor installed on the supply side of a service or within a service equipment enclosure(s), or for a separately derived system, that ensures the required electrical conductivity between metal parts required to be electrically connected. This definition was added to the NEC.
