MOUNTING AND WIRING INSTRUCTIONS

CAUTION: For fixtures labeled for outdoor and wet location use, provide a water-tight seal between the fixture and the mounting surface by using silicone or similar caulking.

NOTE: Underwriters Laboratories (UL) does not require all fixtures to have ground wires. These fixtures meet all UL specifications.

1. Turn off power at circuit box to avoid possible electric shock.

NOTE: If post does not have mounting holes, follow step 2. Otherwise skip step 2 and proceed with step 3.

2.Place fitter (A) over post (B). Mark post (B) using fitter holes as guide. Remove fitter (A), drill 1/8” hole into post (B) at each mark.

3.Pull wires up from post (B) and thread through fitter (A).

4.Identify color coding of fixture wires (see figure 2).

5.To connect wires, take black fixture wire (group A from fig. 2) and place evenly against black post wire. Do not twist wires.

6.Fit wire connector (C from figure 1) over wires and twist until there is a firm connection. If wire connector (C) easily comes off, reattach and check again for a firm connection.

7.Repeat steps 5 and 6 with the white (group B from fig. 2) fixture wire and white post wire.

8.Place ground wire from fixture evenly against ground wire (metal or green wire) from post (B).

9.Repeat step 6 for ground wires.

FIXTURE ASSEMBLY INSTRUCTIONS

1.Place fitter (A) over post (B) (see figure 1).

2.Secure with mounting screws (D).

3.Remove screws (E) from cover (F) and remove cover (F).

4.Install lamp(s) (G) into socket base (H).

5.Replace cover (F) and secure with screws (E).

6.Turn power back on at circuit box.

Fixture includes photocell which turns on at dusk and off at dawn, and cannot be disabled.

W-261 specifications

The Westinghouse W-261 is a notable advancement in the realm of nuclear power technology, representing a significant milestone in the evolution of pressurized water reactors (PWRs). As part of the Westinghouse family of nuclear reactors, the W-261 is primarily known for its enhanced safety features, operational efficiency, and adaptability to various energy demands.

One of the key features of the Westinghouse W-261 is its compact design, allowing for a smaller footprint compared to traditional nuclear reactors. This makes it particularly appealing for locations where space is a constraint. The W-261 is engineered to deliver a power output typically in the range of 1,000 megawatts, making it a robust option for meeting the energy requirements of large urban areas or industrial applications.

The reactor employs advanced modular construction techniques, which streamline the assembly process and reduce construction time and costs. The use of pre-fabricated components facilitates quicker installation and commissioning phases, providing an overall boost to project economics.

In terms of safety, the Westinghouse W-261 incorporates several state-of-the-art technologies designed to ensure the highest levels of operational security. The reactor features a core catchment system that can contain any potential core material in the event of an extreme accident. Additionally, the passive safety systems allow for natural circulation of coolant, eliminating the need for active intervention in many emergency scenarios. This self-reliant cooling mechanism operates even without external power or human intervention, thus enhancing the safety profile substantially.

The reactor’s core is designed to utilize advanced fuel technologies, including high-density fuels that prolong fuel life and enhance thermal efficiency. This not only reduces the frequency of refueling outages but also minimizes the quantity of waste generated, contributing to a more sustainable nuclear energy future.

Moreover, the W-261 is equipped with sophisticated monitoring and control systems that leverage digital technologies for real-time data assessment. These systems improve the operational decision-making process, enabling swift adjustments to the reactor’s performance based on fluctuating demand or operating conditions.

Overall, the Westinghouse W-261 stands out in the nuclear energy sector for its innovative technologies, focused on safety, efficiency, and sustainability. As the world increasingly turns to renewable energy solutions, the design and operational principles embodied in the W-261 represent a compelling option for meeting future energy demands while prioritizing environmental stewardship.
