Duct Banks
The conduit and conductors in the duct bank for primary and secondary distribution on commercial and multi-unit sites, sized and routed with the building’s load in mind.
Underground electrical wiring, from the utility to the panel
Duct banks, service runs and pad-mount transformers, carried by the same crew that wires the building, on one schedule.

Sound familiar?
The duct bank.The service run.The transformer pad.
Split them from the building electrical and you get a handoff at the building line that someone has to reconcile later.
A site’s electrical infrastructure should answer to one contractor and one schedule.
Our scope
A building’s electrical system starts well before the building line.
The service run from the utility connection, the duct bank carrying primary and secondary distribution, the pad-mount transformer that steps it down — that infrastructure is electrical work, and LuMar Electric carries it as part of the same scope as the panels and the branch wiring inside.
For a general contractor or developer, that means the underground distribution and the building electrical answer to one contractor and one schedule, instead of being split across a handoff where the two have to be reconciled later.
We do the electrical, not the dig. Excavation, trenching and backfill stay with your site contractor; once the trench is open, our crew puts in the conduit, pulls the conductors and makes the connections.
Underground scope
From the utility connection to the panel
The below-grade electrical work we carry alongside the building scope, coordinated with the site schedule and with the utility.
Underground Service Runs
Underground service installation from the utility connection through to the building, terminated and tested by the crew that carries it inside.
Pad-Mount Transformers
Supply, installation and termination of pad-mount transformers, coordinated directly with NB Power or Maritime Electric.
Site Lighting
Parking lots, walkways, yards and building exteriors — pole and wall-mounted site lighting, fed from the underground distribution.
Utility Coordination
Working the service application, the inspection sequence and the utility’s schedule so energization is not the thing holding up occupancy.
Multi-Unit Distribution
Underground servicing for housing communities and multi-building developments, from the site distribution through to each suite.
Why it matters
One contractor, one schedule, one point of accountability
The distribution is one scope
The duct bank, the conductors and the panels they land in are designed and installed as one system, under one foreman, rather than divided at the building line.
Sequencing that holds
The crew pulling the underground service is the crew terminating it inside, so the below-grade work is sequenced around the electrical schedule it feeds.
Accountability that doesn’t split
If something below grade needs to change, it is one contractor’s call to make and one contractor’s cost to carry.
Why LuMar
We know the electrical scope can’t be the reason a schedule slips.
From temporary power on day one to final inspection, our crews work alongside the other trades on multi-unit and commercial builds across New Brunswick and PEI.

Questions
What people ask us
Don’t see yours? Call the office and ask a licensed electrician.
What underground work do you carry?
Duct banks for primary and secondary distribution, underground service runs from the utility connection, pad-mount transformers, site lighting, and underground distribution for multi-unit developments.
Do you do the excavation?
No. We do the underground electrical wiring: the conduit, the conductors and the connections, from the utility to the panel. Excavation, trenching and backfill stay with your site contractor.
Do you coordinate with NB Power or Maritime Electric?
Yes. Pad-mount transformers are supplied, placed and terminated in coordination with the utility, and we work the service application and inspection sequence.
Where has LuMar done this before?
The Tannery Place transformer pad — a new 750 kVA pad-mount transformer installed with NB Power — and The Village at Jonathan Park, both in Moncton.
Split scopes cost the most at the end
If it waits
- Two contractors reconciling a handoff at the building line
- Energization becomes the thing holding up occupancy
- A below-grade change with nobody clearly responsible
When it’s done right
- Underground and building electrical as one system
- Sequenced with the site schedule and the utility
- One foreman, one point of accountability
- Proven on completed Moncton projects
Planning a site with underground servicing?
If your project involves an underground service, a duct bank, a pad-mount transformer or site lighting, talk to our commercial team early — the sequencing decisions get cheaper the sooner they are made.
