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.
