In this video, I’ll discuss the “System Bonding Jumper” (SBJ), its function, and its importance to ensure a safe electrical installation! This video is an ex...
1 de nov. de 1998 · The main bonding jumper completes the ground-fault return circuit from the equipment through the service to the source as is illustrated in Figure 5-4. 3. Connecting the grounded service conductor to the grounding electrode conductor. Under certain conditions given in Section 250-24 (a) (4), it is permitted to connect the grounding electrode ...
28 de jul. de 2011 · One of the revisions to the 2011 NEC involves a new definition for a common term: bonding jumper, supply-side. A supply side bonding jumper is a conductor on the supply side or within a service or separately derived system to ensure the electrical conductivity between metal parts required to be electrically connected (Fig. 1).The method used to size bonding jumpers depends on their location in ...
6 de feb. de 2020 · The purpose of the main bonding jumper is to fasten the EGC (equipment grounding conductors) to the neutral conductor of the electrical service. In other words, it carries the ground-fault current from the service enclosure as well as from the equipment grounding system that is returning to the source. You can read more about the main-bonding ...
20 de abr. de 2023 · Bonding jumpers are used to establish electrical continuity between two or more components of an airplane and are made of a highly conductive material like copper. Electricity travels through conductive objects and because it will always take the path of least resistance, bonding jumpers are designed to carry electric current from one point to ...
11 de ene. de 2022 · Section 250.24(B) requires that “an unspliced main bonding jumper shall be used to connect the EGC and the service disconnecting enclosure to the grounded conductor” and section 250.24(D) further clarifies that “a grounding electrode conductor be used to connect the equipment grounding conductors, the service equipment enclosures and the grounded service conductors” so there is no more ...
Code Change Summary: Revised code language on main bonding jumper material. In the 2020 NEC ®, main bonding jumpers are now permitted to be made of aluminum and copper-clad aluminum.Technically, the materials weren’t prohibited before, but they weren’t specifically mentioned either, except in Table 250.102(C)(1) which specifies the minimum size main bonding jumper permitted based on the ...
