Equipment hookups
Power for commercial and industrial equipment, including transformers, panels and disconnects, from Martinez Electric LLC. We’re based in Derry, NH and take jobs in New Hampshire, Massachusetts and Maine.
What we do
Machines, compressors and other heavy equipment often need more power, or a different voltage, than the building’s outlets give. That can mean a new circuit, a disconnect at the machine, a new panel or a transformer.
- TransformersMounted and wired, like the warehouse job in the photos.
- Panels and disconnectsMounted on strut and wired to the equipment.
- Equipment circuitsPower run to each piece of equipment.
- Service upgradesWhen the building needs more capacity.
Before you call
Have the equipment’s nameplate details handy (voltage, phase and amps), and know where it will sit.
