• Sandwich construction in feeder sections
• Single-bolt bridge joint design

Voltage Options

• 240V systems (120/208V 3-phase, 4-wire)
• 600V systems (277/480V 3-phase, 4-wire)

Typical Plug Amperage Ratings

• 30A
• 60A
• 100A
• 200A
• 400A
• 600A

Breaker Compatibility

CP2 plug-in units commonly support legacy Cutler-Hammer breaker frames including:

• EHD / FDB / FD (15–150A)
• JD / JDB (up to 250A)
• KD / KDB (up to 400A)
• LD / LDB (up to 600A)
• TRI-PAC frames

Best suited for: Older industrial plants still running original SAFETYBUS installations.

CP4 SAFETYBUS (Introduced 1985)

CP4 was introduced as an improved version of CP2. It retained compatibility while enhancing safety and performance.

What Makes CP4 Different?

• Sandwich busbar design in plug-in sections
• 130°C Mylar insulation
• UL-recognized case ground path
• Improved bridge joint package

The Big Compatibility Advantage

CP4 busway accepts CP2 and CP3 bus plugs. That makes it more flexible in facilities with mixed generations of SAFETYBUS.

Voltage & Amperage

• Available in 240V and 600V systems
• 30A – 600A+ plug-in units

Best suited for: Facilities upgraded in the mid-1980s through early 1990s.

Pow-R-Way Busway (Introduced 1971)

Pow-R-Way is a different design platform entirely. While introduced around the same era, it uses a different construction method and plug geometry.

Key Features of Pow-R-Way

• Full sandwich busbar construction (feeder and plug-in)
• Bolt-end/slot-end joint design
• Silver-plated joint and contact surfaces
• Ratings up to 5000A (system dependent)

Important Warning

Pow-R-Way bus plugs are NOT interchangeable with CP2 or CP4 systems.

This is one of the most common ordering mistakes in the field.

Best suited for: Higher-capacity systems and facilities that transitioned out of SAFETYBUS.

Side-by-Side Comparison

How to Identify What You Have

Before ordering a replacement bus plug, confirm:

• Busway nameplate information
• Style or shop order number
• Voltage rating (240V vs 600V)
• Required amperage
• Breaker frame type
• Plug-in vs bolt-on configuration
• Load orientation (left or right)

Correct identification prevents costly mistakes and downtime.

Final Takeaway

CP2 = Original SAFETYBUS
CP4 = Improved SAFETYBUS (backward compatible with CP2 plugs)
Pow-R-Way = Different system entirely

When the Skyline Tower fire in St. Paul, Minnesota displaced hundreds of residents and left the high-rise without power, getting the building back online quickly and safely became a top priority. For residents, restoration meant more than lights—it meant stability, security, and a path back to normalcy.

To make that happen, NAC Mechanical & Electrical Services partnered with EMSCO to source the temporary power equipment required to restore service to the building. With essential systems down and repairs expected to take time, NAC turned to EMSCO for a fast, reliable solution they could count on.

Understanding the Challenge

Large residential complexes like Skyline Tower rely on intricate electrical systems that distribute power across dozens of floors, elevators, and life-safety infrastructure. After a major fire, these systems can be severely compromised—making it unsafe to reconnect to the grid until inspections, testing, and repairs are completed.

That’s where temporary power comes in. A well-designed temporary system provides a safe, controlled way to energize key building operations—everything from emergency lighting and water pumps to heating, ventilation, and staging areas for cleanup crews.

But designing and deploying a temporary power setup for a 24-story building is no small task. It requires high-capacity distribution equipment, coordination between multiple teams, and the ability to deliver components fast—because every hour without power adds risk and disruption for residents and staff.

The Solution: Equipment That Restores Reliability

To support NAC’s recovery plan, EMSCO supplied a Square D 3000A MLO panel, along with (3) 800A feeds and (1) 1200A feed. This configuration formed the foundation of a temporary power restoration system that will safely support essential building operations while permanent repairs are underway.

These components were carefully selected to match the site’s temporary load demands and compatibility requirements—ensuring seamless integration once installed. EMSCO’s team confirmed functionality and performance through its standard reconditioning process, verifying that each piece met OEM specifications and safety standards before shipment.

Because EMSCO maintains one of the largest in-stock inventories of reconditioned electrical equipment in the country, NAC didn’t need to wait weeks for a manufacturer lead time.

When deciding on an amperage rating for your bus plugs, keep in mind your system's electrical load requirements, the maximum current the bus plug can carry, and the possibility of future extension. Using the proper amperage rating reduces overloading, improves safety, and extends the life of your electrical components.

2. Should I choose fusible or breaker style bus plugs for my system?

Answer:

Your special needs will determine whether you use fusible or breaker style bus plugs. Fusible bus plugs are inexpensive and can take greater fault currents, but they require fuse replacement after usage. Breaker style bus plugs are resettable and have customizable trip settings, which reduces downtime and increases operating flexibility; still, they are often more expensive upfront.

3. How important is proper grounding for bus plugs, and what options are available?

Answer:

Correct grounding is necessary for electrical safety and system performance. It protects against electrical faults and surges, lowering the risk of equipment damage and providing compliance to safety regulations. To maintain a safe and stable electrical environment, be sure that the bus plugs you purchase have sufficient grounding options that meet the requirements of your system.

4. What voltage ratings should I consider when selecting bus plugs for my electrical system?

Answer:

Check your electrical system's voltage needs for safe compatibility with bus plugs. To guarantee safe and efficient operation, the bus plug's voltage rating must be equal to or greater than the system operating voltage. Common voltage ratings include 120V, 208V, 240V, 480V, and 600V. To avoid malfunctions or safety issues, check whether the bus plugs you choose are capable of handling the voltage in your system.

5. Are there benefits to using reconditioned or inspected and safety-tested bus plugs compared to new ones?

Answer:

These options can provide significant cost savings while still offering reliability and performance equivalent to new components. Reconditioned bus plugs undergo thorough testing to make certain they meet industry standards, making them a practical and economical choice for maintaining and upgrading your electrical system.

Certification is a requirement for any professional conducting electrical work, but with so many options available, it’s easy to become confused. As an electrician ponders his career, he may wonder which direction is best.

As you consider your licensing options, here are a few benefits of each of the most popular electrician certifications. Each state has its own licensing requirements, so check with your governing licensing board to determine what you will have to do to reach each level.

Assistant Electrician

Many electricians start out as an apprentice, working while they achieve their certification.  An apprenticeship program is generally a multi-year process that combines work with classroom learning. Many technical schools with electrician programs offer apprenticeship programs to allow entry-level electricians to gain on-the-job experience while still learning the information they’ll need to do the job.

An electrician is required to work a minimum number of hours for completion, usually collecting industry standard apprentice-level rates for the work. The apprentice may be required to work with a local company to ensure he gets the minimum hours per week he needs to complete the program. Until he achieves his license, the apprentice will be required to work under the supervision of a licensed electrician.

Certified Electrician

Once an electrician has hundreds of hours as an electrician, he’ll qualify to supervise assistant electricians and apprentices. This level of certification also requires a minimum number of hours of safety training. Once an electrician advances to this level, he is responsible not only for his own safety, but the safety of those under his supervision.

An electrician will generally be required to pass a qualifying exam before advancing to this level, but having this certification can qualify him for more advanced jobs. This is a great way for an electrician to move forward in his career, bringing in higher pay and gaining additional respect.

Master of Electrician

Eventually, an electrician may choose to advance to “master” level in order to oversee projects and earn a more lucrative paycheck. A minimum level of experience is necessary to qualify for this certification, as well as an extensive education in worksite safety and building regulations. A master electrician is often required to oversee a project, as well as supervise other electricians.

Not all electricians will choose to advance to master level. Some electricians are born leaders, while others prefer to work as part of a team. Once he has his master certification, an electrician often takes on greater responsibility.  Some masters decide to open their own business, employing electricians and apprentices, while other masters work directly for contractors.

At any level, an electrician tackles challenges with ease, keeping worksites safe and working in collaboration with other electricians. Whether an electrician chooses a residential or commercial career, he has many opportunities for advancement within that career. With so many career paths available, the life of an electrician can include the exact types of jobs he wants. An electrician should check with his local governing boards to determine the exact requirements he’ll be expected to meet before he can achieve certification.
