Bonding Strap Electrical Panel

So the bonding strap.

Bonding strap electrical panel.

Pictured is a bonding screw on a metal mobile home frame. If the panel does not have the ground and neutral isolated do you need the bond screw. At left is the cable tv system and the bonding conductor clearly visible. However if this 200 amp main breaker panel can t be immediately installed on the.

If a person connects two pieces of machinery there is a potential for electrical shock. Grounding bonding 2 in our example the service equipment for the home is the 200 amp main breaker panel. This is a sub panel 3 wire feed and the ground going to the water line. Discount on the sense home energy monitor for subscribers.

Pictured at left is a ground rod stuck up out of the. I the panel is a subpanel it goes in on the ground side to bond the panel to ground incase it ever got charged right. The grounds and neutrals are seperated but the bonding strap is attached. Notice the two conductors.

That is your path for fault current to flow and that low impedance path is why a breaker will trip in the event of a fault. And it will take both paths. However they are not the same thing. The main reason for bonding within electrical equipment is to ensure the safety of workers.

I e green wire anywhere downstream of the service panel e g bonding them inside a sub panel then the current will have two paths to take. The national electrical code nec has prohibited re grounding the neutral after the service since the 1923 edition. Http sense refr cc bensahlstrom my favorite qo 200amp main panel 60 spaces. Panels are supplied with split insulated neutrals with an insulated cross strap for service entrance applications the neutral must be bonded by using the bonding strap supplied with the panel for non service entrance subpanel applications the panel may be installed with the bonding strap not connected to the neutral separate ground bars.

That grounding bar is fastened directly to the back of the metal electrical panel and then the panel is connected to the neutral conductor from the utility company by way of the main bonding jumper.

Electrical bonding is the practice of intentionally electrically connecting all exposed metal items not designed to carry electricity in a room or building as protection from electric shock if a failure of electrical insulation occurs all bonded metal objects in the room will have substantially the same electrical potential so that an occupant of the room cannot touch two objects with.

Bonding and ground straps are terms that people often make the mistake of using interchangeably. One goes to the telephone ground one goes to the grounding terminal in the electrical distribution panel box. The neutral and the egc.
