A junction box is an essential part of the electrical wiring systems for homes and commercial buildings. These metal or plastic boxes house and safely protect a structure's electrical connections. The electrical casings come in .
I have a question about using a 4 wire SER feeder cable to the main panel. I did work as an electrical apprentice but didn't learn a lot about grounding and bonding the main . It would be nice to relocate the power meter and fuses from their current location if possible. They don't normally use armoured cable. What DNO area are you in? your profile says Bristol so I think its western power. This document provides you . I have a question about using a 4 wire SER feeder cable to the main panel. I did work as an electrical apprentice but didn't learn a lot about grounding and bonding the main panel or electrical meter. I've only seen 3 wire service entrance cables to residential panels. In the main panel I understand the ground and neutral are connected. I've seen a 4 wire main residential panel on a site and the neutral and ground were separated.
An experienced electrical contractor has told me that you don't have to run the 4 wire feeder but that a 3 wire service entrance cable is allowed provided you do the necessary bonding and grounding at the house. One of the most essential Chapter 3 wiring methods for residential electricians in the National Electrical Code (NEC) is service entrance (SE) cable. Its primary purpose is to be used as a “main” feeder for the (building or premises) aerial service drop or underground feeder connection to dwelling units. Option #1 and #2 - Sub-panel main lugs at top of panel. Service wire can enter from side of sub panel or bottom. (I'm not sure if option #2 would work because I need to bend the #4 copper from the breaker in the main panel down towards the bottom to exit the panel)The current NEC code requires a 4-wire feeder so there is a separate grounding connector between the Main and Sub panels. The neutral and ground are not bonded in the subpanel.
Synopsis: A step-by-step guide to selecting, sizing, locating, and installing the main components—the meter base, main breaker, and breaker panel—of a new residential electrical system, including a discussion of how to size and install the . You can get extension boxes (that size box with an open back designed to stack on an existing box). The deeper 4 x 4 x 2.125" box is 30 cubic inches. The larger 4-11/16" (120mm) square box is 42 cubic inches* All of my 6 or 7 load cables will enter the top of the panel, but there are only 4 small punchouts and one large 2.5" punchout on the top of the breaker side of the box. Due to the narrow dimensions, there is no room to add more punchouts.
