Siemens value pack load centers are provided with a combination flush/surface mount cover, a main breaker, aluminum bus bars, and Insta-Wire neutrals. Insta-Wire neutrals include a patented feature that allows for the screws to ship from the factory in the raised position, eliminating the need to back out the screws which saves labor. Included in the value packs are three Q120 breakers and one Q230 breaker. The Q120 breaker is a single pole, 20A breaker. The Q230 is a double pole 30A breaker. Ground bars are not included in this device and must be purchased separately if needed. If a ground bar is needed use one of the EC2GB series ground bars.
