AST383R

Overview

The Hoffman AST383R is a Type 1 splitter trough enclosure designed for indoor electrical distribution. Constructed from mild steel with a powder-coated gray finish, it measures 36 inches in length, 6 inches in width, and 4-1/2 inches in height. Rated at 85 Amperes, this unit facilitates the splitting of feeder circuit conductors into multiple branch circuits. The assembly includes pre-installed terminal blocks, a single-point ground lug, a ground bar kit, and splitter block assemblies to streamline installation.

Feature Summary

• Facilitates splitting of feeder circuit conductors into multiple branch circuits
• Includes pre-installed terminal blocks and splitter block assemblies
• Features a single-point ground lug and ground bar kit
• Constructed from mild steel with a protective powder-coated finish

Applications

• Indoor electrical distribution systems
• Splitting feeder circuits into branch circuits
• Industrial panel preparation
• Commercial wiring infrastructure

Procurement Notes

Verify that the specific order matches the AST383R model number to ensure correct dimensions and amperage rating. Confirm that the required accessories, such as the included ground bar kit and splitter block assemblies, are present in the shipment. Check for any shipping damage to the powder-coated finish upon receipt. Ensure compatibility with existing feeder and branch circuit requirements before finalizing procurement.

Selection Notes

Select the AST383R when an indoor NEMA 1 rated splitter trough is required for distributing power from a main feeder to multiple branches. This model is suitable for applications needing a 36-inch section with an 85-Amp capacity. Consider the included pre-installed components for faster installation compared to bare enclosures. Ensure the environment is indoors, as the Type 1 rating does not support outdoor exposure.

Part Context

The AST383R belongs to the Hoffman AST series of splitter troughs, which are designed to automate panel preparation by providing pre-drilled and tapped sections. These units help optimize material usage and labor costs by creating ready-to-populate enclosures. The series typically includes various lengths and configurations to suit different electrical distribution needs within industrial and commercial settings.

Replacement Considerations

The AST384R is listed as a related splitter block product from Hoffman Enclosures, Inc., but specific substitution details are not provided in the source data. Verify dimensional compatibility and amperage ratings if considering alternative models. Consult official manufacturer documentation to confirm interchangeability with other splitter trough variants.
