Panduit- Compression Grounding Solutions

Grounding is a critical functioning part of the electrical system. Now, the integrity of your grounding system is dependent upon your connectors withstanding the environment where they are installed. To ensure reliability, maximize safety and speeding up installation ensures that a grounding system will provide you with the greatest value, something that we know is important to all of you.

Connection reliability is critical to the integrity of a grounding and bonding system in the long-term. The Institute of Electrical and Electronics Engineers (IEEE) developed this standard as a means of qualifying permanently installed grounding connectors. Panduit released a white paper, which you can download HERE, which highlights the importance of implementing a solution approach to optimize the performance of grounding connector systems. This white paper also explores Panduit’s StructuredGround Direct Burial Compression Grounding System and how it combines the installation efficiencies of a compression system with the long-term reliability and safety of connections that meet IEEE Std. 837. In this article, we will take a closer look at their Compression Grounding System, the features and benefits and how it would help you.

MCI-A Cables – Perfect Marriage of AC and MC Style Cables

What’s the Differences Between AC and MC Cables?

The current construction of Armored Cables (Type AC) that is approved by UL 4, has an aluminum bonding wire in contact with the metal armor that provides a low-impedance ground path that is required for the proper operation of overcurrent protection devices. This style cable was in use for many years before the introduction of Metal Clad Cables (Type MC).

Traditional Metal Clad Cables utilize one or more green copper grounding conductors and the armor is not an approved equipment grounding means. This is one of the major differences between the two styles of cable. In addition, Type MC Cables also utilize a polypropylene assembly tape rather than the Kraft paper tape on individual conductors that is used on traditional Type AC cables.

As technology advanced, so too did the construction of Metal Clad Cables. Over the years, contractors realized the benefits to using Type MC cable versus Type AC, however, the need for the armor to be an approved equipment ground still persisted.

The birth of MCI-A Style Cables

In the late 2000s, a new style of Type MC Cable was designed that incorporated full-sized bare aluminum ground wire plus the armor as the equipment grounding means. This cable was referred to as Type MCI-A, referencing the style of fitting needed in order to ensure the bonding wire was properly installed. The MCI-A cables are the ideal fit for a contractor that prefers Type MC Cables with the benefit of the armor/ bond wire ground path. An additional benefit of MC Cables is that you are not limited to the number of conductors within the armor. Per UL 4, AC cables may only have a maximum of four circuits, whereas this limitation does not apply to MC Cables.

Special attention should be paid to terminating Type MCI-A cables as the aluminum bonding wire must maintain contact with the armor upon termination. There are several ways to do this, as noted by AFC Cable Systems installation instructions. MCI-A style cables are now common in the electrical industry and also come in healthcare facility (HCF) versions.

AFC Cable Systems introduced their Type MCI-A style cables in 2012, MC-Quik® Cable and MC-Stat® Cable for healthcare. In addition to the armor/ bond wire ground path, AFC also provides labor savings to the contractor by eliminating the overall polypropylene assembly tape, instead a protective covering is extruded directly onto each individual conductor. Removing the overall tape eliminates the time to remove it to access the conductors and eliminates the waste of the scrap.

ATEX Directive: What do you need to know?

What is ATEX Directive and what does it mean for you?  As of July 2003, organizations in the EU were required to follow these directives to protect employees from risks associated with explosive atmospheres. Ultimately, ATEX was adopted to protect workers. Should this mean anything to you in the United States? Good question. Local companies are impacted when they develop and manufacture equipment for use in hazardous locations in the EU.

Here is an example:

A Missouri company builds machines for export to hazardous locations in Europe. This company must understand and meet the minimum requirements for ATEX, even though their facility is not at all impacted by the ATEX directive.

What is an explosive atmosphere? In the workplace, it can be caused by flammable gases, mists or vapors or by combustible dusts. These explosions can lead to death as well as significant damage to people, machinery and the surroundings. Using the correct equipment is necessary to minimize the risk of explosions. A few examples of workplaces with explosive atmospheres include chemical processing, spraying of paint and varnishes, LPG storage and filling, milk drying and flour production.

There are two ATEX directives, one for the manufacturer and one for the user of the equipment.

  • ATEX 95 EQUIPMENT directive 94/9/EC:
    Equipment and protective systems intended for use in potentially explosive atmospheres.
  • ATEX 137 WORKPLACE directive 99/92/EC:
    Minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres.

appleton-productsWhat is required?

First, you must identify areas where explosive atmospheres may occur and classify them into zones. These classifications will be dependent on size and location, the likelihood of an explosive atmosphere existing, and its persistence if it does.

Next, select equipment and protective systems appropriate for each zone. Appleton Group offers a range of customizable flameproof enclosures that carry ATEX and IECEx Certifications. They are designed for use in Zone 1 and Zone 2 areas, where flammable gases or vapors are present, either continuously or intermittently, and in Zone 21 or 22 areas where flammable dusts are present.

appleton-plugs

Appleton also offers Flameproof Plugs and Sockets that are ATEX and IECEx Certified. They can be used in hazardous locations where plugs and sockets are used with portable or stationary electrical equipment. They are also used where weatherproof and robust equipment is required or in Zones 1, 2, 21 and 22 environments in the oil and gas industry.

If you build and ship to Europe and are interested in learning more about ATEX requirements, you can contact Mike Kelsch at mkelsch@frenchgerleman.com or Craig Reynolds at creynolds@frenchgerleman.com for more information.
