To support our members and the contractors who serve them, Todd‑Wadena Electric Cooperative provides easy access to wiring diagrams for our load management equipment. These resources are designed to help installation and a smooth setup process.
Please note that these diagrams are offered as a reference tool. TWEC is not responsible or liable for any personal injury or property damage related to the wiring or operation of load management equipment. We strongly recommend that all installations be completed by a licensed and bonded electrical contractor.
All wiring must comply with the National Electrical Code (N.E.C.) and must be inspected by a state electrical inspector before TWEC can complete the final checkout of the installation.
