VI. Electrical

DANGER

Positively assure all electrical connections are unpowered before attempting installation or service of electrical components or connections of the boiler or building. Lock out all electrical boxes with padlock once power is turned off.

WARNING

Failure to properly wire electrical connections to the boiler may result in serious physical harm.

Electrical power may be from more than one source. Make sure all power is off before attempting any electrical work.

Each boiler must be protected with a properly siz ed over-current device.

Never jump out or make inoperative any safety or operating controls.

The wiring diagrams contained in this manual are for reference purposes only. Each boiler is shipped with a wiring diagram attached to the front door. Refer to this diagram and the wiring diagram of any controls used with the boiler. Read, understand and follow all wiring instructions supplied with the controls.

A.General. Install wiring and electrically ground boiler in accordance with authority having jurisdiction or, in the absence of such requirements, follow the National Electrical Code, NFPA 70, and/or CSA C22.1 Electrical Code.

B.A separate electrical circuit must be run from the main electrical service with an over-current device/disconnect in the circuit. A service switch is recommended and may be required by some local jurisdictions. Install the service switch in the line voltage “Hot” leg of the power supply. Locate the

service switch such that the boiler can be shut-off without exposing personnel to danger in the event of an emergency. Connect the main power supply and ground to the three (3) boiler wires (black, white and green) located in the junction box at the inside top of the boiler jacket. If a low water cutoff is to be used, connect the low water cutoff so that all 120V power to boiler is interrupted if the low water cutoff’s switch opens.

C.Refer to Figures 28 and 29 for details on the internal boiler wiring.

NOTICE

This boiler is equipped with a high water temperature limit located inside the internal wiring of the boiler. This limit provides boiler shutdown in the event the boiler water temperature exceeds the set point of the limit control. Certain Local Codes require an additional water temperature limit. In addition, certain types of systems may operate at temperatures below the minimum set point of the limit contained in the boiler.

If this occurs, install an additional water temperature limit (Honeywell L4006 Aquastat) located in the system piping as shown in the Water Piping and Trim Section of this manual. Wire as indicated in the Electrical Section of this manual.

NOTICE

All wire, wire nuts, controls etc. are installer supplied unless otherwise noted.

SCG specifications

Burnham SCG, short for Burnham Smart City Grid, represents a groundbreaking initiative aimed at reshaping urban landscapes through the integration of modern technologies and sustainable practices. Situated in the heart of a growing metropolis, Burnham SCG embodies the principles of smart city design, focusing on creating an efficient, interconnected environment that enhances the quality of life for its residents.

One of the key features of Burnham SCG is its extensive use of Internet of Things (IoT) technology. This infrastructure enables real-time data collection from various sensors strategically placed throughout the city. For instance, smart streetlights equipped with sensors adjust their brightness based on ambient light conditions and pedestrian activity, effectively reducing energy consumption. This use of IoT extends to waste management, where smart bins signal when they are full, optimizing collection routes and minimizing fuel consumption.

In addition to IoT, Burnham SCG places a strong emphasis on renewable energy sources. The city integrates solar panels across public buildings and utilizes wind turbines in designated areas, contributing to a significant reduction in carbon emissions. Furthermore, an advanced battery storage system ensures that excess energy generated during peak production times is efficiently stored and used during high-demand periods, promoting energy resilience.

Transportation in Burnham SCG embraces the future with integrated smart mobility solutions. A robust network of electric vehicle charging stations encourages the adoption of eco-friendly transportation. The city also features a user-friendly app that provides real-time information about public transport schedules, bike-sharing availability, and traffic conditions, making it easier for residents to navigate their daily commute.

The urban design of Burnham SCG prioritizes green spaces and walkability. Urban planners have designed parks and pedestrian-friendly pathways that encourage outdoor activities and community engagement. These green areas not only enhance urban aesthetics but also contribute to improved air quality and biodiversity.

Lastly, community involvement stands at the core of Burnham SCG’s framework. The city regularly engages its residents through public forums and digital platforms, ensuring that their voices are heard in decision-making processes regarding urban development and sustainability initiatives.

In summary, Burnham SCG is a visionary model of a smart city that integrates technology, sustainability, and community engagement. With its innovative features and forward-thinking policies, it sets a benchmark for future urban developments around the world.
