Good quality disconnect

Would Recommend

Good product, have used several on 100 amp services, I only wish there were more spaces on neutral bus to accommodate ground rods, water main, ground, neutral, and bonding, but whatever inspectors seem fine with it.

Lid doesn't open after installation

Would Not Recommend

Purchased this item with the appropriate hub, however once the hub is installed, the screws from the hub prevent the door from opening. Unless Siemens has a different solution, I will need to cut the screws down in order to make the lid work. 2 stars because it technically does what it is supposed to do and works once screws are modified.
