Discover how Mauro Electric installed a 1200A 3 Phase 480V service for Lenz Composting Station in Stanwood, WA, ensuring efficient and reliable operations.


At Mauro Electric, we pride ourselves on delivering high-quality electrical solutions for a wide range of industrial projects. Recently, we had the opportunity to work on an exciting project for the new Lenz Composting Station in Stanwood, WA. This case study details our process for installing a 1200A 3 Phase 480V service, highlighting the challenges we faced and the solutions we provided to ensure a successful installation.

Project Overview

The Lenz Composting Station required a robust and reliable electrical system to support its operations. The facility needed a 1200A 3 Phase 480V service to power its equipment, ensuring efficient and uninterrupted operation. Mauro Electric was tasked with designing and installing this critical infrastructure.

Initial Assessment and Planning

The first step in the project was a comprehensive assessment of the site and the specific electrical requirements of the composting station.

  • Site Evaluation: We conducted a thorough evaluation of the site to determine the optimal location for the electrical service entrance and equipment placement.


  • Load Calculation: Our team performed detailed load calculations to ensure the new electrical system could handle the station's demands without risk of overload or failure.


  • Coordination with Stakeholders: We collaborated closely with Lenz Composting Station's management and other contractors to align our plans with the overall project timeline and requirements.

Designing the Electrical System

With the initial assessment complete, we moved on to the design phase, focusing on creating a system that was both efficient and scalable.

  • System Design: Our engineers designed a 1200A 3 Phase 480V service tailored to the specific needs of the composting station. This included selecting appropriate transformers, switchgear, and distribution panels.


  • Compliance and Permits: We ensured that our design met all relevant electrical codes and standards. Necessary permits were obtained from local authorities to proceed with the installation.

Installation Process

The installation phase was executed with precision and attention to detail, ensuring that all components were installed correctly and safely.

  • Equipment Installation: We installed the transformers, switchgear, and distribution panels, making sure that all components were securely mounted and properly connected.


  • Wiring and Connections: High-quality wiring was used to connect the various components of the system. Our team meticulously ensured that all connections were secure and compliant with safety standards.


  • Testing and Commissioning: After installation, we performed rigorous testing to verify the system's functionality. This included load testing and safety checks to ensure reliable operation.

If you’re feeling the pinch from rising energy costs, the expert electricians at Mauro Electric Inc have advice on how to lower your electric bill. We understand how important it is to keep electric bills under control, and that means managing electricity usage. How To Lower Your Electric Bill Practical tips to lower your electric bill and save money Energy efficient lighting Switch to LED bulbs because LEDs consume significantly less energy and last much longer. Maximize the natural light that comes into your home during the day. Open the curtains and blinds and reduce the need for artificial lighting. Turn off the lights when you leave the room. It’s a great, and money-saving, habit. Address phantom energy users Unplug electronics when not in use. Devices like TVs, computers and chargers use energy even when you turn them off. Unplug or use power strips to easily turn them off and stop their phantom energy usage. Smart power strips automatically cut off power when not in use. They are “set and forget” money savers. Optimize the building’s HVAC system Schedule regular maintenance to ensure the system is running efficiently. Invest in programmable thermostats to automatically adjust temperatures. Caulk and weather strip windows and doors to prevent air leaks. Insulate your walls and attic to prevent drafts. Upgrade appliances to lower your electric bill Invest in Energy Star appliances because they consume less energy. Smart appliances can be controlled remotely and are optimized for energy efficiency. Water heater efficiency Lower the water heater temperature to 120° to reduce energy consumption. Insulate the water heater. Fix any leaky faucets because they waste water and energy. Schedule an electrical system check-up with Mauro Electric, Inc Outdated wiring is inefficient and could be a fire hazard. We can inspect the system and suggest necessary upgrades. Our inspection will ensure your electrical system is properly grounded; this helps prevent energy waste and protect appliances from power surges. If the electrical panel is outdated, it may be inefficient and costing you money in wasted energy. We can upgrade the panel to a more modern, energy-efficient system. Consider solar power This may be a bigger investment than you want to make, but solar panels are a long-term solution to significantly reduce – or eliminate – your electric bill.
