With our decentralized network of locally operated branches, strong community ties, and commitment to personalized service, City Electric Supply (CES) has always forged our own path to meet customer needs. Now, we’ve pioneered a way to deliver panelboards and switchboards with speed and precision: CES One-Line Service.
CES One-Line Service
CES One-Line Service is a one-stop shop for panelboards and switchboards in record-breaking time. Trained by Siemens, our dedicated team has been perfecting the craft of in-house panelboard and switchboard assembly and distribution since 2019. The fine-tuned process ensures that contractors can not only meet tight deadlines but also take on challenging jobs with confidence.

Fast delivery
CES One-Line Service sets the new standard for order fulfillment and delivery at one week or less. The traditional lead time for panelboards and switchboards can range anywhere from six weeks to nine months. For electrical contractors who can’t wait that long, we provide the solution to get them from diagram to done in days.
Trusted results
Say goodbye to surprises on the jobsite. With a track record of over 99% accuracy, customers can trust us to get it right the first time. Trained personally by Siemens, an industry leader in switchgear, contractors will receive the same quality they know and trust on a revolutionary timeline.

Easy process
Traditionally, takeoff is a time-consuming and painstaking process. With CES One-Line Service, contractors can skip takeoff entirely. No more listing out every breaker, panel and fuse — all we need is the one-line drawings to identify the materials, assemble them correctly, and deliver the order to you.
Full inventory
Waiting on materials to build panelboards and switchboards is a thing of the past. We have $26 million of inventory ready to go, so orders can go from drawing to assembly with no hold-ups. Six strategically placed fulfillment centers across North America are equipped to maintain extensive inventory and reduce wait time.
Centralized process, coast-to-coast
Each of our six fulfillment centers has a dedicated CES One-Line Service team, trained by Siemens to follow one well-tested process. This centralized approach empowers us to consistently deliver high-quality panelboards and switchboards wherever a customer needs them. It combines the power of local branches and well-stocked fulfillment centers, backed by the expertise of Siemens and CES.
