Square D To Supply Massive New Google Data Centers — Leading To Long Lead Times For Customers

We’ve been hearing from some of our customers who have tried to place orders for new stock from Square D that they’ve encountered long lead times (several weeks to months) and have instead turned to EMSCO to quickly get the industrial electrical equipment they need. It turns out the long lead times from Square D are a result of being a supplier for a massive construction project from Google to build up to 11 new data centers, of which Square D has won the contract to provide the electrical infrastructure.

Aside from EMSCO’s massive inventory of industrial electrical equipment, we have the best lead time in the industry. If you are down and need to get up and running ASAP, we’re the place to call! With a major food producer down, EMSCO was able to ship a Square D NW40 main breaker lineup with multiple distribution sections and breakers same day to get them up and running again right away. Not only that, but we also completed a Square D Model-6 Motor Control Center lineup in 2 days after a company was down and couldn’t wait the long lead time for new. That MCC included starter, feeder and VFD buckets.

Whether it’s a single section of busway, a single breaker or bus plug, or a complete lineup, EMSCO has you covered to get you back up and running ASAP! We’re standing by 24 hours for all your after hours emergencies. Simply give us a call anytime (1-800-328-1842) and we’ll be ready to jump into action.

A Brief Introduction to Motor Control Centers

It's been a while since we discussed one of our main product categories in an overview post. In the past, we've covered topics like bus plugs to provide general information about the products EMSCO offers. In this post, we'll delve into the basics of Motor Control Centers (MCC).

Basics of Motor Control Centers (MCCs)

At its core, a Motor Control Center consists of a series of buckets housed within a larger structure. In industrial and manufacturing environments using electric motors, a system is necessary to control these motors, and that's where the motor control center plays a crucial role.

How They Operate

Feeder buckets are responsible for powering and controlling the electric motors, typically with one bucket per motor. Given that industrial processes often involve numerous electric motors, multiple buckets are required to manage the entire system. The structure serves as the vertical housing, conveniently holding and controlling all feeder buckets in a central location.

The buckets within the structure come in various sizes and configurations, such as fused or circuit breakers. Additionally, these buckets are fully removable, providing flexibility for the electric system to adapt to changes in industrial processes. For instance, adding or removing motors is simplified by adding or removing buckets from the structure or swapping them out for the appropriate components.

In Need of Parts?

If you're looking to replace, upgrade, or install a new MCC system, your search ends here. We offer a wide range of vertical sections of motor control centers, ranging from 400 amperes to 3000 amperes, with main or main lug compartments. Our extensive stock includes all major brands like Square D, GE, Allen Bradley, and more. With a plethora of buckets in stock, both fusible and breaker styles, in sizes 0-6, single and twin feeder buckets, EMSCO is certain to have the components you require.

An Introduction to Bus Plugs

Bus plugs are a critical component of industrial power distribution systems. This blog post explores what bus plugs are, how they function, and the advantages they offer over traditional wiring methods. Learn how bus plugs can enhance flexibility, safety, and efficiency in your facility's power distribution.


In most residential and commercial settings, power is distributed through hardwiring in the walls. In industrial settings, however, the large open floor plans make it difficult to distribute power in this way. That's where bus duct and bus plugs come in.

In industrial settings, bus duct is often used to distribute power to various areas of a facility. Bus duct [also known as busway] is essentially metal enclosures that contain conductors for distributing electricity and generally come in 10-foot sections that connect to one another to create the exact length necessary for a run. They can be installed overhead or under the floor, and they're designed to be flexible, so they can be easily repositioned or rearranged as needed.

However, just having bus duct isn't enough to distribute power to all the equipment in a facility. That's where bus plugs come in.


Bus plugs are essentially large industrial electrical plugs that connect to a section of bus duct overhead and then feed electricity down to the equipment below.

Bus plugs typically come in a variety of sizes and styles to fit different types of bus duct and equipment. They're designed to be easy to install and remove, so they can be quickly repositioned or replaced if needed.


One of the benefits of using bus plugs is that they allow for greater flexibility in terms of the layout of a facility. Because the bus duct and bus plugs can be easily repositioned, it's possible to change the layout of a facility without having to rewire the entire electrical system. This can save a lot of time and money in the long run.

Another benefit of using bus plugs is that they provide a higher level of safety compared to traditional hardwiring. With hardwiring, it's possible for a fault to occur in the wiring, which can lead to electrical fires or other hazards. With bus duct and bus plugs, the conductors are contained within metal enclosures and the bus plugs are equipped with either fuses or circuit breakers, which provide an extra layer of protection against faults and other issues.

Overall, bus plugs are an important component of industrial power distribution systems, allowing for greater flexibility and safety compared to traditional hardwiring.

We hope this has served to give a basic understanding of what exactly a bus plus is, how it works, and why it is used. If you’re looking for replacement bus plugs for your system, look no further! EMSCO stocks the largest selection of used and reconditioned bus plugs from all the major manufacturers (GE, Square D, and more) and from all vintages, from obsolete to modern systems.
