- Generators should be used only in strict accordance with manufacturer specifications and in compliance with local codes.
- Portable generators should be operated not only outside, but well away from buildings due to risk of carbon monoxide being pulled into structures.
Powering your home or business
- A portable generator should not be connected to power your entire home unless you have received all required approvals for use of a transfer switch and it has been installed by a trained professional.
- Failure to meet this requirement can risk public safety, your neighbors’ safety, TNMP line crew members’ safety and your safety.
- Non-portable generators can be used to power all or part of your entire home or business, but also require transfer switches upon installation.
Transfer switches: steps to take
TNMP allows use of open transition (break-before-make) transfer switches.
Ask your electrical contractor to prepare a one-line diagram of the proposed design (download example PDF).
Prepare an e-mail that includes:
- The service address, including city name.
- Your name and daytime contact info.
- Your contractor’s name and daytime contact info.
- Information on the installation.
- The one-line diagram.
- Specifications sheet for proposed transfer switch.
Send the e-mail to backupgenerators -at- tnmp -dot- com.
TNMP’s engineering department will review your proposal and one-line diagram, and will follow up with any questions.
If no issues are identified, TNMP will send you a letter of “NO OBJECTION” via e-mail that will allow your electrical contractor to proceed. The letter also will provide other critical information.
You will need to request a temporary disconnection by TNMP personnel. Fees will apply.
