The Accu-CT® family of current transformers, ACTL-0750 and ACTL-1250 series are UL listed, so there are no specific conditions of acceptability (as there would be for a UL recognized component). However, these CTs must be used in a way that does not exceed their electrical ratings and they must be installed following the installation instructions.

Although conditions of acceptability are not generally needed when using the Accu-CT family of CTs with a WattNode meter, the following information may be helpful if you are using them in other applications or seeking approval to use them with other devices.

GENERAL

These devices are single-phase open type air cooled encapsulated current transformers. They may be provided with a burden resistor that enables AC voltage secondary output.

They are suitable for use in 55°C ambient in accordance with the requirements of IEEE Standard C57.13-1993 and CAN/CSA 60044-1.

CONDITIONS OF ACCEPTABILITY

  1. The transformers shall be installed within equipment that will provide an acceptable enclosure.
  2. The suitability of the lead wires shall be determined in the end use product.
  3. These transformers have not been tested for accuracy, impulse and mechanical tests, only temperature and dielectric voltage-withstand tests were performed.
  4. The acceptability of the mounting means for these transformers shall be judged in the end use.
