What is a breaker spacer?
This DIN mount spacer is designed to go between Circuit breakers and other DIN mount electrical equipment items. Particularly useful where an item may get over heated if the air flow around the item is not maintained.
What is a dead front on an electrical panel?
An electric panel will generally have one or two covers. Panels with two covers have an outer cover (which will open to the side or upwards) and an inner cover, called a “Dead Front”. The dead front cover normally has the slots / knockouts for the breakers to fit into.
What are knockouts on an electrical panel?
Knockouts are partially stamped, quarter-size openings in the electrical boxes that service such things as outlets and switches. Once removed, a knockout allows electrical wires to be run in and out of the box.
Where is the ground in a breaker box?
Inside the breaker box you’ll see a bar across the box with a series of holes and screws. In most breakers boxes, there will be two of these with one for the white neutral wires and one for the green ground wires. Screw the bare end of the ground wire to this bar, which is known as the ground bus bar.
What clearance is required around electrical panels?
3 feet
The Occupational Safety and Health Administration (OSHA) and the National Electrical Code (NEC), require that electrical panels have a minimum of 3 feet (36 inches) of clearance and a minimum headroom of 6.5 feet or the height of the equipment whichever is greater.
What is arc chute?
Arc chute is a set of parallel arranged metal plates which extinguishes the arc formed when the circuit breaker interrupts the high electric current. It is also known by other names such as arc dividers or arc splitters. It is an important component of the circuit breaker.
How many amperes can an I line panelboard handle?
However, when installed into HCP and HCPSU panelboards they are only rated 800 amperes maximum due to restricted wire bending space. For Surgelogic™ I-Line plug-on SPD information, starting on Digest Externally Mounted SPDs .For field-installable I-Line door kits, see the Supplemental and Obsolescence Digest, Section 4.
Which is neutral current transformer for I-line panelboard?
1200 A, including neutral Current Transformer (CT) for 3Ø4W systems Equipment Ground Bar Kits—HCJ, HCM, HCP, HCP-SU (single row), HCR-U 1.5 in. for mounting on wide side of I-Line panelboard used with HNM1BL and HNM4BL as a filler plate on the wide side of the panel (HCP, HCP-SU and HCRU).
How many amperes can I put on a HCRU panelboard?
S33930, S33931, SL1200P5, SL1200P6, SL1200P7, SL Kits are rated 1200 A and may be applied to 1200 ampere loads when installed into HCRU panelboards. However, when installed into HCP and HCPSU panelboards they are only rated 800 amperes maximum due to restricted wire bending space.
