Rigid ladder or trough structure that supports power and instrument cables along a route.

**In short:** Rigid ladder or trough structure that supports power and instrument cables along a route. JJ Projects sources it to the specification the buyer names. Typical reference, standards: NEMA VE 1; NEC (NFPA 70) Article 392.

## Specification references

- Standards: NEMA VE 1; NEC (NFPA 70) Article 392
- Types: Ladder and solid-bottom trough
- Materials: Galvanized steel, aluminum or stainless steel
- Accessories: Fittings, covers, splice plates and supports

> Typical references only. The governing specification is the one on your purchase order or datasheet.

## Typical uses

- Routing power and instrument cables along pipe racks and buildings
- Cable runs in substations, control rooms and process units
- Supporting cable between equipment and junction boxes
- Outdoor and corrosive areas, using aluminum or stainless trays where galvanized steel is not enough

## What to include in a request

A request with these details can be quoted without a round of questions. Send what you have and we will ask for the rest.

1. Type: ladder or solid-bottom trough, and ventilated or not
2. Width and loading depth, from the cable fill calculation
3. Span and load class under NEMA VE 1, from the support design
4. Material and finish: hot-dip galvanized steel, aluminum or stainless steel such as 316
5. Straight section length and the fittings: elbows, tees, crosses, reducers, drop-outs
6. Covers, splice plates, hardware, supports, and bonding or grounding provisions
7. Quantity by length and fitting count, and the documents required

## Questions

### How do I choose the tray width?

From the number and diameter of the cables and the fill limits that apply, such as the NEC Article 392 rules for cable tray. The electrical designer sets the width and depth. Send the cable schedule if you want help checking it.

### Galvanized steel, aluminum or stainless steel?

Hot-dip galvanized steel is the common economical choice and is strong. Aluminum is light and resists corrosion in many outdoor areas. Stainless steel is chosen for aggressive chemical or marine environments. The project specification names the material.

### What is a NEMA VE 1 load class?

NEMA VE 1 rates cable tray by the working load it carries over a given support span, in classes such as 8A, 12B or 16C that combine a load and a span. The class on your drawing sets the tray and the support spacing.
