COMBINATIONS

The CASE division of The Durham Company, manufactures the socket/breaker combination units to meet city utility codes and allow for additional distribution to shop, barn or out buildings. If you need a gang combination for an apartment building or office space The Durham Company can supply the units. The units range in amps from 100 -320.

 

 The Durham Company transfer switches assist in many applications from back-up generators at hospitals or schools to keeping production going at manufacturing facilities and agricultural entities when the power goes out. These units range from 100 to 800 Amps and can be installed for multiple services. The design of the transfer switch will ensure there will be no back feed into the system to keep your employees and customers safe.
