Bonding jumper

Rules for bonding jumper installation are given in electrical code regulations. Typically, these require a jumper at any place where the continuity of a bonding system might be interrupte for example, where metallic conduits join an enclosure through. The main bonding jumper is one of the most critical elements in the safety grounding system.

This conductor is the link between the grounded service conductor, the equipment grounding conductor and in some cases, the grounding electrode conductor. The primary purpose of the main bonding jumper is to carry the ground-fault current from the service enclosure as well as from the equipment. Do you know what a main bonding jumper is for? Where is the main bonding jumper located? How big should that bonding jumper be?

What is an Equipment bonding jumper? GROUNDING AND BONDING BONDING STRAPS AND KITS. Two-hole compression lug end bonding jumpers. Although not rigidly enforce 250.

B) seems to indicate the main bonding jumper be connected likewise. In addition, the enclosure can not be used to carry neutral current. This definition was added to the NEC. As the size of the ungrounded conductors increases, so does the size of the bonding jumpers. A supply-side bonding jumper is a conductor on the supply side or within a service to ensure the electrical conductivity between metal parts required to be electrically connected.

Because of the deletion of the definition “grounding conductor” from Art. A)(1) that had previously used this term. A bonding jumper for a supplemental grounding electrode is required to be not smaller than AWG. The NEC defines the term ground as the earth. RACK GROUND JUMPER KITS.

Term Image (600x400) BONDING STRAPS. An equipment bonding jumper is used for bonding equipment and a supply-side bonding jumper is used for bonding equipment on the supply side of the service. The complete definition of these terms can be found in Article 1of the N. The supply-side bonding jumper is part of the ground-fault current path. When the system bonding jumper is not located at the derived source of the separately derived system, the grounded conductor (neutral) serves as part of the supply-side bonding jumper during a ground-fault condition. Platform Automation Solutions.

A conductor on the supply side : or within a service or separately derived system to ensure the electrical conductivity between metal. Wiley Electronics BONDING JUMPER 6. Used to provide electrical connection between (2) rails. Register or with your Rexel Account for price or to order.

System bonding jumper 2. Equipment grounding conductor 3. Supply-side bonding Jumper 4. Bonding Jumper , Supply-Side. Grounding electrode conductor 5. At a grounded-type wye transformer, we install a system bonding jumper at a location from the transformer to the first disconnecting means on the secondary side. Cable Runway is available in tubular side rails that are lightweight yet strong and solid-bar side rails for maximum strength. Both styles utilize rungs made of tubular steel.

Finishes include standard black powder coating and a range of optional colors. The bonding jumper for multiple disconnecting means is located The minimum diameter of galvanized pipe allowed for a grounding electrode is Which of the following is true of the neutral in a grounded system? Now, it seems much discussion goes on about the importance of removing the neutral-ground bonding jumper at the genny (in deference to the main bonding jumper at the service panel), one reason being to preempt parallel current path for normal neutral return current.

Everything is good to go.
