We're able to take parts with 5 to 9 different set ups and get them done in 2 set ups. Our Haas machine completely changed how we build and design our components by being able to control this process in-house. HAAS was the clear choice for us when deciding to bring machining in-house. The time we save on set ups pays for the machine.
I have a double gang junction box which will house two switches, one controlling main lights which are at 277V and the other controlling decorative lighting at 120V.

We are using the existing pad mounted xfmrs which have the space in the bottom to stub up conduits. When these are elevated the transformers will be open on the bottom so we want to put a galvanized box on the bottom that we can connect the conduit to.
Installation Options: Overhead or underground entrance, underground entrance and bottom exit and pad-mount or wall-mount. SCCR: 50K up to 400 Amps units, 65K 600–3000 Amps units. Applications: Used where a long-run junction box or service termination is needed. Combo Options: Breaker or fuse pullout (available at 400 Amps)
