I understand that. Trace websites based in the US specify UL listing on their equipment. Does this hold true in the DR, or do they sell an uncertified version here?
Testing equipment used in the DR must be connected to UL power devices in order to certify the test results from that equipment.
Can you tell me which other brands, models or sizes sold in the DR have the UL listing? If not UL listed, CSA is equivalent outside of the US without further UL testing.
