Electrical Equipment LTL Shipping Guide
Freight Class for Electrical Equipment
To estimate your shipment, use the Electrical Equipment Freight Class Calculator.
The Electrical Equipment Freight Class Examples use the current 13-tier density scale, effective July 19, 2025, and range from Class 55 to 100.
These are density-based estimates.

Electrical Equipment shipment comparison
Electrical Equipment Freight Class by Shipment Type
Electrical equipment ranges from dense transformers to tall, comparatively light control electrical equipment and switchgear sections. Enclosure size, internal bracing, moisture barriers, protruding buswork, and no-stack requirements can change occupied cube and handling needs.
| Electrical Equipment shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Transformers | Bolted to a heavy skid with terminal protection | Very high | Limited | Distribute concentrated weight and protect bushings, lugs, and cooling components. |
| Control panels | Foam-protected crate around the enclosure | High | Usually non-stackable | Brace doors and internal components and protect switches and display faces. |
| Switchgear sections | Tall enclosed crate or factory shipping base | Medium to low | Non-stackable | Maintain upright orientation and shield bus bars, breakers, and cable compartments. |
| Electrical electrical equipment and controls | Palletized or crated enclosure | Medium | Limited | Prevent door movement and protect conduits, fans, and protruding hardware. |
electrical equipment shipping options
Choosing a Shipping Method for Electrical Equipment
The right service depends on electrical equipment size, packaging, stackability, and handling needs.
| Electrical Equipment shipment | Common shipping option |
|---|---|
| Compact transformer on a reinforced skid | Heavy standard LTL |
| Crated control panel or electrical electrical equipment | Crated LTL |
| Tall switchgear or distribution section | Specialized upright LTL |
| Oversized transformer or multi-section lineup | Dedicated or specialized service |
Large, irregular, non-stackable, unusually valuable, or specially handled electrical equipment shipments may need carrier review before booking.
Electrical Equipment Packaging, Stackability, and Damage Risk
Electrical Equipment Packaging
- Bolt heavy equipment to a rated skid and brace tall enclosures against tipping.
- Protect terminals, bushings, buswork, breaker faces, switches, fans, and conduit fittings.
- Use moisture barriers, desiccants, and sealed outer protection when electrical components are exposed to humidity.
Electrical Equipment Stackability
- Compact fully enclosed crates may permit limited stacking only when the crate is engineered for top load.
- Tall control enclosures and switchgear sections should normally be treated as non-stackable.
- Do not top-load transformers with exposed bushings, cooling fins, or terminal assemblies.
Electrical Equipment Moisture, Terminal, and Shock Protection
- Prevent moisture intrusion, enclosure distortion, broken terminals, and shock to breakers or relays.
- Brace doors and internal components so latches and hinges do not carry transit loads.
- Confirm upright orientation, shock limits, and declared value for sensitive control equipment.
Before Requesting an Electrical Equipment Freight Quote
How to Measure a Packaged Electrical Equipment Shipment
- Measure after factory bases, skids, crates, moisture barriers, and top protection are complete.
- Include bushings, conduit fittings, cooling sections, doors, lifting eyes, and crate framing.
- Use the total packaged weight of the enclosure, internal components, base, crate, and accessories.
Electrical Equipment Freight Quote Checklist
- Measure the finished skid, pallet, enclosure, or crate containing the electrical equipment.
- Record the total packaged weight of the complete electrical-equipment shipment.
- State whether the crate is engineered for top loading or must remain upright and non-stackable.
- Include photos of terminals, bushings, control faces, doors, cooling sections, moisture protection, and lifting points.
- Confirm forklift capacity, upright handling, loading-dock, liftgate, and specialized rigging requirements.
Freight Planning Calculators
Calculate and Plan Your Electrical Equipment Shipment
Use the freight class, density, pallet, and linear-feet calculators to plan your packaged LTL shipment.
Freight Class Calculator
Estimate freight class from packaged dimensions, weight, and density.
