Faster Assembled
Panels,
Built to Order

Introducing Our In-House Assembly Shop, now operating at our King of Prussia location.

Standard Lead Time? Forget 6-8 Weeks

At Colonial Electric Supply, we know speed matters. Factory-assembled Square D panels typically take 6 to 8 weeks or more. With our new in-house Square D Panel Shop, we can deliver NQ/NF and I-Line panelboards in just a few days. No long waits. No project delays.

  • Fast Turnaround: Panels assembled in-house in days, not weeks.
  • Square D Quality: Assembled exclusively with Square D components.
  • Assembled Solutions: NQ/NF and I-Line panelboards tailored to your project’s exact needs.



Your Project
Delivered on Time

With decades of experience in electrical solutions, we don’t just supply products, we help solve problems. Our dedicated Square D Panel Assembly Shop gives you direct access to custom-assembled panels without factory wait times, backed by Colonial Electric’s expertise and support.

Keep up to date with the latest products, special offers and news.

Colonial Electric Supply and it's divisions is a product supplier only. We do not serve as project engineers. Rather, we work with project engineers towards their design goals. We expect customers to obtain and use products in accordance with the manufacturer's intended use. We are not responsible for product malfunction due to misuse, with the exception of replacement per stated warranty conditions.
