Our control boxes, motors, complete pump assemblies and electrical accessories are tested by independent
product safety and testing organizations to ensure compliance with the US National Electric Code (NEC) and/
or Canadian Standards Association (CSA) standards. Underwriters Laboratories Inc. and CSA are the agencies
with whom we contract. They have now agreed to eliminate overlapping efforts through an agreement which
allows either to test to the other’s standards. This is good for manufacturers and consumers as overlapping
independent testing is very expensive.
Unfortunately, there is a great deal of misunderstanding associated with the Agency Listings and their marks or
logos. By meeting specific safety requirements products can be either UL Listed or UL Recognized. The UL mark
in a circle signifies that a product is UL Listed (approved) for its intended use by Underwriters Laboratories Inc.
Radios, televisions, CD players, fans and small appliances are a good example of UL Listed products.
The lesser known and most misinterpreted UL mark is the backwards , signifying a UL Recognized
Component. This is used on products that are combined to create a complete assembly. In the Submersible
Pump Industry, pumps larger than 2 HP are shipped as separate water ends and motors due to weight and
length restrictions of major shippers. Therefore the products cannot carry a logo, but only the backwards
logo since they are Components of a complete system. According to both UL and CSA, electrical inspectors
should consider the assembled products as approved if the motor and water end are matched by HP, i.e. a ½ HP
Water End on a ½ HP Motor.
The 4” CentriPro motors are tested by Canadian Standards Association to UL 1004 and 2111 as well as to CSA
standards 77 and 100. They carry a logo. This indicates they are CSA Listed for the USA and Canada, i.e.,
tested by C.S.A. to U.L. and CSA standards.
CentriPro, single-phase, 4” motor control boxes carry a listing.
Testing by the Canadian Standards Association is denoted by the CSA logo or .
Per their recent agreement UL can test products sold in the USA and/or Canada, conversely, CSA can test
products sold in Canada and/or the USA.
