- If damage to a customer’s property is caused as the direct result of some action not taken by HMLP after HMLP became aware of a potential problem, and had areasonable opportunity to address and correct the problem, HMLP will reimburse the customer for the fair market value of the damaged property or the reasonable costs to repair the damaged property.
- HMLP shall not be responsible for any damage caused by lightning, surge damage that occurred due to damage to HMLP’s lines or equipment caused by adverse weather, or any other damage resulting from an Act of God.
- HMLP shall not be responsible for any damage caused, in whole or in part, by the negligence of a third-party for whom HMLP had no responsibility for or control over.
10. Notice of Trouble
11. Standby and Resale Service
The following general requirements apply to Customer generating facilities designed to operate directly connected to HMLP’s electrical system (parallel operation) and those which are designed to operate isolated from the HMLP’s system (non-parallel operation.) Requirements and specifications for various types and sizes of Customer facilities shall be obtained from HMLP prior to installation.
Standby generation (non-parallel operation) may be installed by the Customer to supply all or part of the load in the event of a service interruption. The Customer’s wiring shall be arranged so as to conform to all current NEC, NESC and other state (527 CMR 12 Current Edition) or local codes, and prohibit the interconnection of the Customer’s alternative source of supply with HMLP’s service. This will require the installation of a double-throw switch or its equivalent as approved by HMLP and the Town of Hingham Inspector of Wires.
NOTE: Precautions must be taken where alternative means of generation are employed, whether emergency or otherwise, to eliminate the possibility of electrical connections between the HMLP service and the Customer’s alternate source of supply (e.g. truck docks, etc.) The Customer must notify HMLP and provide electrical details of the generator installation and isolation from the HMLP system.
Standby generation (parallel operation) requires notification and approval of HMLP before installation begins. Prior to the installation of any auxiliary generator facilities (e.g. wind turbine, solar panels, etc.), the Customer must fill out the appropriate HMLP application to provide interconnection details and to obtain approval for the facility’s protective and synchronizing equipment arrangements.
