Aluminum EMT Means Contractors Can Install an EMT System that Won’t Rust

Connect Aluminum EMT with Bridgeport.

Electricians have often asked, “Why doesn’t an EMT manufacturer make corrosion-resistant tubing that won’t rust.” Now with aluminum EMT, contractors have their wish and can put away their rigid conduit threaders and reamers. 

Aluminum EMT is the perfect material choice for indoor or outdoor, damp, wet or exposed environments. With Bridgeport’s line of Listed Zinc Alloy EMT connectors and couplings, contractors can quickly install a lightweight, corrosion-resistant EMT system that won’t rust.

The Bridgeport zinc solution, with aluminum EMT, provides countless advantages for the contractor: inherent corrosion resistance, lighter weight, no dissimilar metal concerns, easy fabrication, and a pleasing appearance. The Listed fittings also make for easy inspections.

Contractors see the advantages of tool-free, quick-install, armored cable connectors

AMC-50QI fittings save electricians time and money.

Contractors want a cable connector that cuts down on both labor costs and installation time and gets the job done right.  

Just ask George Casner, Jr., owner of Casner Electric LLC in Milldale, Conn. Casner explains why Bridgeport’s AMC-50QI fitting is so much better than the old-style, locknut-type connectors that take a long time to install and with no guarantee of a solid connection or proper grounding. “When you lock in the Bridgeport connector, it’s really in there,” Casner stated.

Casner also noted that when feeding the Bridgeport connector into where the cable is going to be grounded, there is less chance of a short circuit or a breaker tripping which can happen with a traditional connector. 

Bridgeport’s AMC-50QI is not only easy to install but easy to remove – a benefit the Connecticut contractor likes a lot. “Sometimes you overload connectors on one side of the panel but find you need to reposition a connection to the back or other side of the panel.”  Casner goes on to explain how the Bridgeport fitting is easy to pop out and reposition.

Really, MC Cable outdoors…?

For some Contractors PVC Jacketed Metal Clad cable has become the better way to deliver power to equipment in wet and adverse locations. Cable manufactures have designed and listed features that make this a versatile, moisture impervious cable choice that gives you the opportunity to run quickly without sacrificing performance. The ease of installing Cable vs. Conduit and wire should be enough motivation to compare material costs and man hours.


2014 NEC permitted uses:

  • Industrial, commercial, and multi-residential buildings
  • For power, lighting, control, and signal circuits
  • Surface mounted indoor or outdoor  
  • Pump applications
  • Branch circuits (parking, rooftop, signage)
  • Concealed or exposed systems
  • In wet locations per NEC 330.10(A) (11) (a)
  • For direct burial in the earth where identified for such use or embedded in concrete per NEC 330.12(2)(a)
  • In assembly occupancies (NEC 518.4)
  • In theaters, audience areas and similar locations (NEC 520.5)
  • As aerial cable on a messenger wire
  • In cable trays (NEC 392)
  • Under raised floors for IT equipment (NEC 645.5)

The cable can be: 

  • Used as branch circuit or feeder wiring for lighting, equipment, control and signaling circuits in wet, dirty or oily conditions.
  • Buried directly in earth or encased in concrete.
  • Surface mounted or trenched for use in site lighting, signage, parking decks or lots, marinas, rooftops and stadium applications.
  • Used for swimming pool pump and motor applications that requires a continuous run for significant labor savings.  


As you can see the suggested uses are vast and in my opinion much quicker to install compared to Liquid tight metal conduit and wire. Our Canadian friends have been installing PVC coated AC for over 25 years, called TECK cable. A variation of jacketed metal clad cable with an inner PVC jacket and stranded copper conductors. The Canadian Standards Association (CSA) designation is “Teck 90”.

For the overall installation to be a win, the connectors must also form a mechanical watertight seal and maintain continuity from the power source to the equipment. Be sure to confirm the connector’s listing (intended uses) along with cable ranges and any installation requirements. Jacketed MC Cable is required to be supported at intervals not to exceed 6-feet and branch circuit cables 10/4 or less within 12 inches of the cabinet or enclosure. The use of Stainless steel straps and hangers will ensure long lasting performance and better workmanship.


Here are some productive ways to use JMC or TECK:

AC unit install

Two connectors, one roll of 10/3 or 8/3 and before you know it, electricians are stripping, connecting and terminating into outdoor disconnects and equipment.

Commercial Kitchens and Restaurants

No problem terminating JMC vertically or horizontally into appliances that are located in tight confined spaces.

Site Lighting

Trenched, laid the cable and caution tape, received Inspectors approval and backfilled in the same day. All in fewer days compared to Schedule 40 PVC conduit and wire.

Pools and Jacuzzis 

Quickly install direct burial and pump rated PVC coated cable with fittings. Bridgeport’s Polyolefin Coated Zinc Alloy connectors are suitable for niche lighting boxes that are in close contact with the ground.

We all know there are many different ways to save time and money. With the use of Jacketed Metal Clad cable contractors are finishing the job faster, in half the time, up to 50% faster than traditional conduit and wire. With less material, even loading the truck is easier.

TYPE "MC-PCS" Cable Fittings Compatibility

There is a new MC Cable configuration on the market called “MC-PCS”. This specialty cable was introduced in late 2014, and was designed to reduce the amount of wiring involved with todays new LED and Fluorescent, SMART dimming systems. 

Since this is a new MC Cable construction, there have been many field questions as to what kind of fittings should be specified for terminating the cable to boxes, enclosures, and lighting fix-tures. Also, there has been some confusion if cable fittings need to be specially Listed for this new cable construction. The cable construction differs slightly from a standard MC Cable, as it contains a separately grouped and insulated, 16/2 control cable, bundled in parallel with the current carrying conductors. This new cable construction has recently been designated by UL as type: “MC-PCS”. The Metal Clad Cable specification UL1569 (PJAZ), is currently poised to be amended to include this new “MC-PCS” designation. 

However, within the current fittings specification of UL514B (PJOX), there is no separate “MC-PCS” fittings category designation, and therefore no specific fittings requirements for “MC-PCS” type cable. This will likely change in the coming year as UL harmonizes all affected specifications. In the interim, there will be no separate “MC-PCS” Listing required for fittings specified to be used with the new MC Cable. The only requirement is that appropriately sized fittings Listed for MC Cable are used. 

Per NEC Articles 330.40, 320.40 & 300.15, ALL cable fittings must be Listed. The Listing evaluations are made with cable constructions and dimensions which were available at the time of evaluation. Among other requirements, UL514B specifies that a cable fitting used with AC/MC/MCI-A cable must have a cable armor stop, which shall prevent the passing of cable armor completely through the throat of the fitting – while allowing the insulated conductors pass through without damage. This cable armor stop may be plastic or metal, or circular or oval. However, no matter what the configuration, the cable stop shall restrict the cable armor from passing through, and allow all of the cable conductors to pass through without restriction. 

Bridgeport Engineering has evaluated the various type MC-PCS cable construction variations, and developed a list of compatible and Listed fittings. These fittings are selected to handle the maxi-mum diameter of the armor, providing a suitable armor stop, while allowing the conductor bundle to pass through. Attached is a table which indicates Bridgeport’s current MC-PCS cable fitting options. Of course, if there are any concerns or questions about a particular installation or specification, please contact the Engineering Department at Bridgeport Fittings.
