Pull Box Installation Cost in 2026: Full Breakdown

> **Quick Answer:** A pull box installed by a licensed electrician typically costs $80–$250 for small boxes (6×6 to 12×12) and $400–$1,500+ for large industrial boxes (36×36 and up), including materials and labor. Actual cost depends on box size, mounting location, conduit complexity, and local labor rates.

Why Pull Box Cost Varies So Much

Ask three electrical contractors what a pull box costs and you'll get three different answers. That's not evasion — it's because "pull box" covers everything from a small 6×6×4 steel enclosure on a single branch circuit to a custom 48×48×12 welded steel box on a utility feeder. The NEC 314.28 sizing rules mean larger conduit = larger box = more material and more labor hours.

Before you put a number on a bid, you need to know the box size. That starts with knowing what your conduits are doing inside the box — straight pull, angle pull, or U-pull. Run the dimensions through the [pull box sizing calculator](/pull-box-sizing-calculator) first, then use this guide to estimate what those dimensions will cost you.

Material Costs by Box Size (2026 Pricing)

These are typical distributor prices for standard carbon steel NEMA 1 (indoor) enclosures from manufacturers like Hoffman, Wiegmann, or Hammond. Prices vary by region and distributor relationship, but these ranges are representative of mid-2026 pricing.

**6×6×4 inches (small branch circuit box)**

- Material: $15–$30

- This size comes up for single-conduit pulls on 20–60A branch circuits with conductors 8–4 AWG in ½"–¾" conduit.

- Wiegmann and similar commodity brands are at the low end; Hoffman at the high end.

**12×12×4 inches**

- Material: $45–$80

- Common for 1" to 1.5" conduit straight pulls and small angle pulls.

- Galvanized steel adds roughly 15–20% to price. Stainless adds 3–5×.

**12×12×6 inches**

- Material: $55–$95

- The extra depth matters when conduit hubs are large or you need room for conductors to lay without binding against the cover.

**24×24×8 inches**

- Material: $120–$200

- This range covers many commercial feeder applications — 2" to 3" conduit angle pulls, service entrance boxes.

- At this size you start seeing meaningful price differences between gauges (12 ga vs 14 ga steel).

**36×36×10 inches**

- Material: $300–$500

- Industrial feeder territory. Boxes this size are often stocked at major electrical distributors in basic configurations but may be special-order for anything with unusual hub patterns.

**48×48×12 inches**

- Material: $600–$900

- Large industrial or utility applications. 4" to 5" conduit runs, 1000 kcmil and up. Lead times of 2–4 weeks are common for non-stock sizes.

- Custom sizes (welded to order) run $900–$2,000+ depending on gauge and hub count.

Labor Costs

Electrician labor rates in 2026 range from about $85/hour in lower-cost markets to $130+/hour in major metros (union scale can hit $150+ with fringes in high-cost areas). These time estimates assume a two-person crew and a straightforward installation.

**Small box (6×6×4 to 12×12×6):**

- Installation time: 1–2 hours

- Labor cost at $95/hour: $95–$190

**Medium box (12×12×8 to 24×24×8):**

- Installation time: 2–3 hours

- Labor cost at $95/hour: $190–$285

- This includes mounting, stubbing in conduit, and conductor management for typically 2–4 conduit entries.

**Large box (36×36×10 to 48×48×12):**

- Installation time: 4–6 hours

- Labor cost at $95/hour: $380–$570

- Ceiling mount or overhead work adds 20–30% to these times.

- Multiple conduit entries on multiple walls — typical on large feeder boxes — add another 30–60 minutes.

**Custom or specialty boxes (anything larger, unusual NEMA ratings):**

- Installation time: 6–12+ hours depending on size and conduit count

- Large custom boxes may require additional support structure, adding material and labor.

Factors That Drive Cost Up

**Mounting location.** Wall mounting at accessible height is the baseline. Ceiling mounting requires lifts or scaffolding and adds 30–50% to labor time on large boxes. Underground or pit-mounted boxes add waterproofing considerations and typically require a higher NEMA rating (3R, 4, or 4X).

**Conduit stub-in complexity.** Each conduit entry requires a knockout punch or a pre-punched hub. For a box with 6 conduit entries on multiple walls, add 30–45 minutes for layout and punching alone if the box isn't pre-drilled.

**Cover type.** Standard screw-on covers come with the box. Hinged covers with latches add $20–$80 for medium boxes, more for large ones. Gasketed covers for wet locations add another $30–$100.

**Painting or finish work.** Standard steel boxes are gray or unpainted. If the installation requires paint matching (industrial process areas, exposed architectural spaces), add $50–$150 for spray can finish or touch-up. Full industrial coatings are a separate line item.

**Conduit material.** RMC fittings for large conduit are expensive — a 3" RMC chase nipple can run $25–$45 each. EMT connectors are cheaper but not permitted in all locations.

Material Grades: When to Upgrade

**Standard carbon steel (NEMA 1):** The default for dry interior locations. Fine for most commercial work. Not suitable outdoors or in wet locations.

**Galvanized steel:** Better corrosion resistance for lightly damp locations, mechanical rooms, parking garages. Adds 15–25% to material cost vs. standard steel.

**Stainless steel (304 or 316):** Food processing, wastewater treatment, marine environments. 3–6× the cost of standard steel. Use only where required — it's overkill in most commercial settings.

**Fiberglass (NEMA 4X):** Outdoor, corrosive, or high-moisture environments where steel would rust out within a few years. 2–4× the cost of standard steel for the same box dimensions. Fiberglass doesn't need painting and outlasts steel in harsh environments. The long-term math often favors fiberglass in coastal or chemical environments.

**Polycarbonate:** Similar applications to fiberglass, but limited to smaller sizes. Not appropriate for large pull boxes due to structural limitations.

Total Installed Cost Examples

**Small commercial job — single 1.5" conduit angle pull, interior wall:**

- 16×16×6 steel box: $85

- Hardware (anchors, nipples, fittings): $25

- Labor: 2 hours × $95 = $190

- **Total: ~$300**

**Medium commercial — 480V feeder, two 2.5" conduits, angle pull:**

- 24×24×8 steel box: $165

- Hardware (conduit hubs, sealing fittings): $60

- Labor: 3 hours × $95 = $285

- **Total: ~$510**

**Large industrial feeder — three 4" conduits, two angle pulls from different walls:**

- 48×36×12 custom steel box: $750

- Hardware (6 hubs, support brackets): $150

- Labor: 7 hours × $110 = $770

- **Total: ~$1,670**

These numbers don't include overhead, profit, permit fees, or inspection costs, which typically add 20–40% for a contractor's final price.

Ways to Reduce Costs Without Compromising Compliance

**Order the right size the first time.** Undersized boxes get rejected at inspection and rework costs more than the original material. Use the [NEC 314.28 box sizing tool](/pull-box-sizing-calculator) to confirm dimensions before ordering.

**Specify standard stock sizes.** Custom boxes are expensive and slow. If your calculation says you need a 22×22 box, a standard 24×24 is the right answer — it's stocked and faster to ship than a custom 22×22.

**Group pull boxes where conduit runs converge.** Instead of two separate 16×16 boxes in adjacent areas, a single 24×24 box serving both runs might be cheaper in total material and labor.

**Use EMT where code permits.** In dry commercial interiors, EMT conduit fittings are significantly cheaper than RMC. The pull box itself doesn't care what type of conduit is entering it.

**Plan for straight pulls instead of angle pulls where possible.** Routing conduit through opposite walls (straight pull) instead of adjacent walls (angle pull) often produces a smaller required box — check both options at the design stage.

When DIY Is (and Isn't) Appropriate

Installing a pull box isn't inherently difficult — it's mechanical work. Mounting the box, punching knockouts, landing conduit, and pulling conductors are all learnable skills.

But a few things make DIY pull box work risky for non-professionals:

- Permit and inspection requirements: most jurisdictions require electrical permits for new circuit work, and inspectors will check NEC 314.28 compliance.

- Conductor handling: pulling large conductors (1/0 AWG and up) through conduit without the right tools and techniques can damage insulation.

- Service entrance work: anything upstream of the main disconnect is utility company territory in most states. Don't touch it.

For branch circuits serving mechanical equipment (HVAC, pumps, compressors), a licensed electrician is the right call — both for code compliance and liability. For a homeowner running a sub-panel feeder in their own workshop, many jurisdictions allow owner-occupied work with a permit.
