Grounding Connection in BESS Containers:
It must be robust enough to handle potential fault currents and must be correctly positioned to ensure effective grounding. The grounding
Large containers such as drums must also be grounded when used as dispensing or receiving vessels. All grounding and bonding connections must be metal to metal. This means all containers of Category 1, 2 or 3 liquids (liquids with a flashpoint lower than 100° F) need to be bonded and grounded during dispensing.
It must be noted that bonding and grounding are required for the containers that conduct electricity, such as those made from metal or conductive plastics. If a container is made from a material that does not conduct electricity, such as polyethylene plastic or glass, bonding or grounding may not be required.
This means all containers of Category 1, 2 or 3 liquids (liquids with a flashpoint lower than 100° F) need to be bonded and grounded during dispensing. This includes non-metallic containers, even though the construction material may not be recognized as conductive (for example, polyethylene).
The grounding connection in a BESS container serves two primary purposes. First, it provides a path for electrical faults, such as a short circuit or insulation failure, to be safely directed into the earth. This prevents the fault from causing damage to the BESS or other connected equipment.
