I have a C1D1 area with a chemical mixer. The mixer consists of a base, vertical turret, and mixing head with a belt driven XP motor. The mixing head has a long shaft with changeable prop. The turret is literally a giant hydraulic cylinder that extends to lift the mixing head assembly (motor included) up in the air about 42" in order to install and remove the temporary mixing vessel (55 gal drum or IBC tote). So, the motor driving the mixer shaft moves vertically 42" every time we mix a batch.
The current installation is using SOOW cord with a TMCX075 series cable connector on either end. Reading the literature, there is no mention of SO type cable having a listing or rating when used with this connector. It has TC, but tray cable is not the same as SO cable, and even if it was, the TC rating is Div 2 only.
Because of this, I feel the installation does not meet code, and have started looking for a suitable replacement option. What I am finding, is that nobody seems to list usage with service cable for these sealed connectors. Reading the code, it looks like I can keep the SOOW cable, and use a generic seal off fitting for rigid conduit that has the C1D1 rating, and then use a generic SO cord grip that is installed into the seal off fitting.
This is based off 501.140 (B) (4) which reads:
In Division 1 locations or in Division 2 locations where the boxes, fittings, or enclosures are required to be explosionproof, the cord shall be terminated with a cord connector or attachment plug listed for the location or a listed cord connector installed with a seal listed for the location. In Division 2 locations where explosionproof equipment is not required, the cord shall be terminated with a listed cord connector or listed attachment plug.
Can anyone out there confirm my interpretation is correct?
