.2.1. For specialised applications, OBO of-
fers its equipotential bonding system type 1809 NR,
made from renewable raw materials with lead-free
contact strip. These offer wide range ad-
vantages over pipe clamps during assembly. They ensure secure contact for all standard
cross-sections.2.OBO “BigBar” equipotential busbar for industrial applica-

tions.2 Residential and office buildings
Even though the environmental conditions residen-
tial buildings and office buildings are less challenging,
here, too, necessary ensure that dangerous
touch voltages can occur. The OBO type 1802 “BigBar” equipotential
busbar can used without problems these situ-
ations main earthing equipotential busbar. With
their rustproof stainless steel tightening strap, they are
suitable for wide range pipe diameters and mater-
ials.
3.1.1 Industrial applications
In industrial environment, particularly important
that the products used are thermally and mechanically
stable.
OBO 1802 “BigBar”:
• Tested with 100 (10/350) per IEC 62561-1
• Can used indoors and outdoors
• Stainless steel and copper versions available
• 5–20 pin versions available
• Quick mounting with carriage bolts
When connecting metallic pipes the equipotential
bonding, earthing pipe clamps such OBO type 927
are generally used
