Commercial Electrical Equipment & Supplies

Common commercial electrical supplies and materials include switchgear, switchboards, panelboards, meter mains, service entrance sections, remote power panels, circuit breakers, bus bars, conduit, wiring, enclosures, metering equipment, and protective relays. DEI Power specializes in the primary power distribution assemblies — switchgear, switchboards, panelboards, SES, and RPPs — built with genuine Siemens components.

Common electrical tools used during installation of commercial power distribution equipment include multimeters, voltage testers, wire strippers, conduit benders, cable pullers, torque wrenches, insulation resistance testers, panel schedules, thermal imaging cameras, and power quality analyzers. These tools are essential when installing switchgear, panelboards, and meter mains in commercial and industrial facilities.

DEI Power offers commercial electrical equipment from 225A up to 4000A across switchgear, switchboards, panelboards, meter mains, and service entrance sections. Voltage configurations include 120/240V, 208Y/120V, 240V, 480V, 480Y/277V, and 415/240V, covering the full spectrum of commercial and industrial power distribution requirements.

DEI Power's products are UL 891 certified for low-voltage switchgear construction, EUSERC approved for utility interconnection, and manufactured as a Siemens Approved OEM. All assemblies comply with UBC, CBC, and IBC seismic zone requirements. Remote power panels also carry Build America Buy America (BABA) compliance, as they are manufactured in Ontario, California.

A switchboard is a large assembly used for main power distribution at higher amperages (typically 400A–4000A), often located near the service entrance. A panelboard is a smaller distribution board that feeds branch circuits within a facility. Both are available from DEI Power in NEMA 1 (indoor) and NEMA 3R (outdoor) enclosures with UL 891 certification and genuine Siemens components.

Most in-stock orders ship within 1 business day from DEI Power's 50,000 sq. ft. facility in Ontario, California, with standard delivery in 3–5 business days and free shipping on all orders. Built-to-order configurations for custom specifications typically carry 4–6 week lead times. Rush and emergency replacement orders are also supported for data centers and critical facilities.
