Power Generation and Uninterrupted Power Supply


Craft Electric & Maintenance provides sales of Kohler, Caterpillar, Cummins / Onan, Generac, and Gillette Generators. The line of Uninterruptible Power Supplies (UPS) include Eaton Powerware, Toshiba, MGE, and APC to name a few. Automatic Transfer Switches (ATS) included from each generator supplier plus ASCO Series.

Our expertise in power generation covers up to 4000 amps of backup power in megawatts for data centers down to small single phase 20KW units.

We can design at fractions of the cost of large engineering firms, weather a simple backup generator with UPS to more complex redundant systems with Main-Tie-Mains, generators backing up generators, or paralleling generator systems.

A few of our data center projects:

This project consisted of a 2000 amp service with one 800 KW generator, with a backup 800 KW generator for a N + 1 backup system.  Paralleling switchgear sequenced the two generators feeding two 1200 amp Automatic transfer switches. The two ATS fed a 1200 amp main tie main which fed distribution equipment and a 450 KVA UPS.

This project consisted of 1.6 megawatts of backup power generated by two 800 KW generators and paralleling switchgear with a 3000 amp service and ATS.  The UPS was rated at 450 KVA.

This project consisted of 3000 amp service with 2.4 megawatts of backup power generated by three 800 KW generators, paralleling switchgear and a 2000 amp ATS.
