Abstract
An electrical service equipment provides electrical service to a building or other similar venue. The equipment includes a cabinet with two portions structured to hold a meter pan and a switch, respectively. The switch is preferably an HCP switch. The portion holding the meter pan includes a subassembly including two horizontal plates and a plurality of buses passing through the plate and adapted to provide connection to the current and voltage transformers of the meter pan.
Claims16
An electrical system providing electrical service to a building or other venue, the system comprising:
- a first portion configured to receive a meter pan for measuring power consumption, said first portion including first power connection members adapted to connect to a first plurality of multiphase power conductors;
- a set of intermediate connectors
- a second portion configured to receive a switch, said second portion being connected to said intermediate connectors and including second power connection members adapted to connect to a second plurality of multiphase power conductors said switch being configured when installed to selectively switch current between said first and second power connection members through said intermediate connectors;
- wherein said first portion includes a transformer subassembly including a first horizontal plate, a second horizontal power plate, said plates being made of an electrically insulating material;
- a first set of buses passing through said first plate, a second set of buses passing through said second plate, each bus including a first portion adapted for connection to one of said intermediate connectors and said power connection members and a second portion adapted to connect to said meter pan;
- wherein said plates are sized and constructed to maintain said buses in a preselected spaced arrangement when said buses are subjected to an excessive short circuit current.
An electrical system providing power to a building or other venue from a plurality of multiphase line conductors through a plurality of multiphase load conductors, comprising:
- a cabinet;
- a first portion configured to receive a meter pan for measuring power consumption, said first portion including first power connection members adapted to connect to a first plurality of multiphase power conductors;
- a set of intermediate connectors
- a second portion configured to receive a switch, said second portion being connected to said intermediate connectors and including second power connection members adapted to connect to a second plurality of multiphase power conductors said switch being configured when installed to selectively switch current between said first and second power connection members through said intermediate connectors;
- wherein said first portion includes a transformer subassembly including a first horizontal plate, a second horizontal power plate, said plates being made of an electrically insulating material;
- a first set of buses passing through said first plate, a second set of buses passing through said second plate, each bus including a first portion adapted for connection to one of said intermediate connectors and said power connection members and a second portion adapted to connect to said meter pan;
- wherein said portions are disposed vertically with respect to each other within said cabinet, and said plates are sized and constructed to maintain said buses in a preselected spaced arrangement when said buses are subjected to an excessive short circuit current.
