What is BS 951?
BS 951 specifies the performance and important mechanical requirements for metal clamps that are used to provide mechanically and electrically sound earthing and bonding connections to metal tubes.
What is a earth clamp?
An earth clamp connects the lead out cable from the energiser to an earth rod. The earth clamp guarantees a secure connection between the energiser and earthing system for optimum electrical conductivity. Secure connection between the earth rod and ground cable. Ensures optimum electrical conductivity.
What does a bonding clamp do in cable?
Terminated bonding and grounding wire come with clips or clamps attached at the ends to secure the wire to grounding surfaces. They help prevent buildup of static electricity to prevent damage to equipment and reduce the risk of electric shock to workers.
What is fitted at every BS 951 connection?
BS 951 clamps must only be fitted to solid pipework not cables. I did a previous post a few weeks ago when I found 951 clamps fitted to a wire armour then did a bit of research into this. An extract from BS951 scope is below: b) bonding conductors to metal tubes of circular.
What is a bonding clip?
Bonding wire is used to create electrical connections between two metal parts, while grounding wire connects a circuit to the earth or another large conductor for protection. Clips and clamps secure bonding and grounding wire to grounding surfaces.
Can you splice bonding wire?
They can be spliced, using any listed device and there are no particular burial requirements.
How far can a ground rod be from panel?
The NEC requires all driven rods to be a minimum eight feet in the earth and for multiple connected rods a minimum spacing of six feet between rods.
Is Earth bonding still required?
Supplementary equipotential bonding (between waste pipes, metallic service pipes and earth connections of bathroom equipment) is no longer required if, and only if, the main bonding between metal service pipes can be proved to be continuous.
