Littelfuse LD5552-2 Power Distribution Block

Product Description

The LITTELFUSE LD5552-2 is a power distribution block designed to split or combine electrical circuits within a panel, enclosure, or distribution assembly. Power distribution blocks provide a reliable termination point for incoming line conductors and outgoing branch conductors, reducing the need for wire nuts or jumper bars. Licensed electricians and electrical contractors typically specify these components during new construction, panel upgrades, or service replacements where organized, code-compliant conductor management is required.

The LD5552-2 is suited for use in commercial and industrial electrical distribution assemblies, as well as residential load centers and sub-panels. It is installed inside enclosures, panelboards, or junction boxes where multiple branch circuits must be fed from a single supply conductor. Electricians use these blocks to maintain clean, inspectable wiring layouts that meet NEC requirements for conductor termination and overcurrent protection coordination.

Key Features

• Splits a single supply conductor into multiple branch circuit connections
• Designed for installation inside electrical enclosures, panelboards, or junction boxes
• Supports organized, code-compliant conductor management per NEC guidelines
• Reduces reliance on wire nuts or improvised jumper solutions
• Suitable for both new construction and retrofit panel work

Compatibility

Designed as an OEM-style replacement or direct-install power distribution block for use in standard electrical enclosures and distribution panels requiring organized multi-circuit conductor termination.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the panel and verify absence of voltage with a calibrated meter before handling any conductors or termination hardware. Ensure all conductors are properly rated for the circuit voltage and ampacity before terminating. Do not exceed the block's rated conductor size or circuit capacity as marked on the device.
