In August 2026 three customers ordered UL 891 low-voltage switchboards from DEI, each a different build: two indoor boards at two service voltages for All Star Wholesale Electric; an outdoor service-entrance board for a county park project, ordered by OSP.com, which had to clear the engineer’s review on a schedule too tight for a 15-week lead time on one component; and an outdoor 1200A meter-main with a utility metering section, ordered by So Cal Circuit Breakers for a solar project.
For All Star Wholesale Electric, an 800A switchboard at 480Y/277V with a Siemens 3VA main and two 400A feeders, plus a 400A main-lug-only board at 240/120V with two 400A feeders and one 200A feeder; both 65 kAIC, NEMA 1, aluminum bus. For OSP.com’s county park project, a 400A service-entrance switchboard at 208Y/120V with copper bus, 65 kAIC, NEMA 3R, a Siemens 3VA main, nine two-pole feeders and a spare provision, an integrated 300 kA surge protective device and an enclosure heater. For So Cal Circuit Breakers, a two-section 1200A meter-main switchboard at 480Y/277V, 65 kAIC, NEMA 3R, tin-plated aluminum bus, with a utility pull and current-transformer metering section and a 1200A LSIG main.

Engineered, fabricated and assembled under one roof in Jurupa Valley, California.
The two boards for All Star Wholesale Electric were delivered on DEI’s own truck 14 days after DEI confirmed the order, and six days after the order was released to production; DEI had ordered their Siemens breakers by two-day air the day it confirmed the order.
For OSP.com, DEI answered the engineer’s review comments on the surge protective device and its breaker, an enclosure heater, nameplates, dimensions and lug sizing, and the review of the resubmittal, dated the day before the order, came back with two notes. A Siemens-made surge protective device carried a lead time of about 15 weeks, so DEI proposed a comparable unit available in two to three weeks, and on the day of the order it bought breakers and a current transformer for next-day air delivery. The park-project board shipped 22 days after the order.
For So Cal Circuit Breakers, DEI’s submittal drawings are dated the day the purchase order was issued, and the 1200A meter-main was ready for the customer’s pickup 24 days after it.
Three switchboard jobs, 400A to 1200A, each shipped or ready for pickup in under four weeks from the order (14, 22 and 24 days), with the dates taken from DEI’s own build records and order paperwork.
