The Canadian Electrical Code stipulates that liquid-tight flexible metal conduit and connectors used in hazardous location applications (Class I, Division 2; Class II; Class III or Zones 2, 20, 21, 22) be marked Heavy Duty as per applicable CSA standard.
The T&B Liquidtight Systems offering now includes a full range of liquid-tight flexible metal conduits and connectors that meets the CSA Heavy Duty certification.
Below conduits have passed the rigorous testing requirements of CSA Standard C22.2 No.56-17 Annex A "Heavy Duty” and can now be used in Hazardous location applications.
Similarly, T&B Liquidtight fittings have passed the rigorous testing requirements of CSA Standard C22.2 No.18.3-12 Annex D "Heavy Duty” and can be used in conjunction with above conduits for a full Heavy Duty solution.
