Underground Duct Bank & Site Lighting

Professional underground duct bank installation and site lighting systems for commercial properties, parking lots, and industrial facilities in Pennsauken, NJ.

Underground Duct Bank Installation

We install underground electrical duct banks for commercial and industrial sites throughout Pennsauken. Duct banks protect your electrical infrastructure from damage, weather, and ground movement while providing room for future expansion. Every installation meets NEC Article 300 requirements and local code.

Our crew handles the full scope: trenching, conduit placement, concrete encasement, backfill, and final grading. We coordinate with utility locates, pull permits, and schedule inspections so your project stays on track.


Site Lighting Systems

Proper site lighting improves safety, security, and visibility for parking lots, walkways, building perimeters, and loading areas. We design and install LED site lighting systems that meet photometric requirements and local ordinances.

Our site lighting services include:

  • Parking lot pole lighting
  • Building-mounted flood and wall packs
  • Walkway and pathway lighting
  • Security and perimeter lighting
  • Photocell and timer controls
  • Emergency lighting systems

Why Underground Infrastructure Matters

Overhead lines are vulnerable to weather, vehicle strikes, and vandalism. Underground duct banks provide a permanent, protected pathway for power, data, and communications. When you need to add circuits or upgrade capacity later, the conduit is already in place.

We size duct banks correctly from the start—accounting for voltage drop, conduit fill ratios, and future load growth. All work is inspected and documented for your records.


Code-Compliant Installation

Every underground and site lighting project is permitted and inspected. We follow NEC standards for burial depth, conduit materials, conductor sizing, and grounding. Our installations pass inspection the first time.

How it works
01

Site Assessment & Design

We review your electrical needs, site layout, and future expansion plans. For lighting, we provide photometric analysis to ensure proper coverage.

02

Permitting & Utility Coordination

We pull permits, coordinate utility locates, and schedule inspections with the local authority.

03

Trenching & Installation

Our crew excavates trenches, installs conduit and duct banks with proper depth and spacing, and sets lighting poles and fixtures.

04

Wiring & Connection

We pull conductors, make terminations, install controls, and test all circuits for continuity and proper operation.

05

Inspection & Restoration

The installation is inspected and approved. We backfill, compact, and restore the site to original grade or better.

Common questions
How deep do underground conduits need to be buried?+

Burial depth depends on voltage and conduit type. Typically, rigid metal conduit under 600V requires 6 inches of cover, while PVC requires 18 inches. We follow NEC Table 300.5 and local amendments for every installation.

Can you add circuits to an existing duct bank?+

Yes, if there is available conduit and the existing system was sized with spare capacity. We can pull new conductors through existing conduit or add conduit if the duct bank was designed for expansion.

Do site lighting systems require photometric plans?+

Many municipalities and commercial projects require photometric analysis to demonstrate adequate light levels and minimize light trespass. We provide these plans as part of the permit package when required.
