Are you sure one of them is not a Neutral ?Ivan001 said:I have two 30x10mm2 Earth busbars in switchboard, both are placed on insulators, but connected through various parts of switchboard (ground terminal, rails, door, mounting plate...)
The purpose of connecting two 30x10mm2 Earth Busbars is to create a larger and more reliable grounding system. By connecting two busbars, you are increasing the surface area of the grounding system, which improves its ability to dissipate electrical currents and protect against electrical faults.
The minimum conductor cross section required for connecting two 30x10mm2 Earth Busbars is determined by the amount of electrical current that needs to be carried through the connection. It is important to ensure that the conductor cross section is large enough to handle the maximum expected current without overheating or causing voltage drops.
The appropriate conductor cross section for connecting two 30x10mm2 Earth Busbars can be determined by consulting with electrical codes and standards, as well as performing calculations based on the expected current and length of the connection. It is recommended to consult with a qualified electrician or engineer for accurate calculations.
No, it is not recommended to use a smaller conductor cross section for connecting two 30x10mm2 Earth Busbars. Doing so can result in overheating, voltage drops, and potential safety hazards. It is important to use the appropriate conductor cross section to ensure the safe and efficient operation of the grounding system.
Yes, there are other factors to consider when connecting two 30x10mm2 Earth Busbars. These include the type of conductor material, the type of connection method (e.g. crimping, bolting), and the environment in which the connection will be made (e.g. temperature, moisture). It is important to follow all applicable codes and standards and use proper techniques to ensure a secure and reliable connection.
