The term supply-side bonding jumper first appeared in the 2011 National Electrical Code as a result of a CMP-5 Task Group regarding the proposed revisions to Section 250.30 for grounding separately derived systems.

Many questions are being raised about the requirements for bonding metal gas piping systems. More specifically, when corrugated stainless steel tubing (CSST) is installed for the gas piping in a building, bonding methods and bonding jumper sizes that are more restrictive than required by the National Electrical Code® are causing some of the confusion and [...]

The CE Code requirements for bonding and grounding are perhaps, the most important safety rules for electrical installations. Each person deemed to be qualified to do electrical work must clearly understand what bonding and grounding is, why it is necessary and how it must be done. And yet the basic principles of these essential code [...]

The answer to this question is yes and no. That sounds like an answer from an inspector, doesn’t it? Yes, it is just a large container of water, but when you mix electrical equipment, such as pumps, heaters, and lighting with this large container of water, there can be problems. Article 680 addresses “…all swimming, [...]

From the beginning, the National Electrical Code has included specific rules that are essential for protection of persons and property. Wiring and protection is covered more specifically in chapter 2 and is so titled. Article 250 provides the specific rules for grounding and bonding electrical systems and equipment. To understand how the grounding and bonding [...]

Article 250 of the National Electrical Code provides the minimum requirements for grounding and bonding. The title of the article was revised in the 2005 NEC development process to reflect what is actually covered by the article. In the past, it seems many viewed the word grounding as an umbrella description, and viewed the concepts [...]

Separately derived systems can be grounded or ungrounded. The primary difference between a grounded derived system and an ungrounded derived system is that no intentionally grounded system conductor exists in an ungrounded system. All conductors derived from these systems are ungrounded conductors. Where the separately derived system is required to be grounded as provided in [...]

In many electrical installations today, some protection needs extend beyond the installation requirements of the Code. Static electricity and the buildup of static charges are major concerns in many installations such as data processing centers, semiconductor facilities, and many hazardous (classified) locations. In the information technology (IT) world, minimizing static electricity and circulating currents is [...]
(1 votes, average: 4.00 out of 5)Canadian Electrical Code, Rule 10-814 is where we find the minimum bonding conductor sizes for electrical circuits. It’s a fairly straight forward rule, simple to understand and it gets used quite a bit, since most electrical circuits require bonding to protect us against fire and shock hazards. But does everyone interpret and apply the rule [...]
