As many of us are involved in designing control panels as well as programming the PLCs that are installed in them, I have a customer who was cited by his inspector for the following:
He uses a GFCI outlet for most of his ICPs. The inspector told him that he must also have a testing schedule and signoff for the testing of the GFCI outlet. I've not heard of this. In my research in the latest UL508A Standard, I can find no reference to testing, or recording results of tests, of GFCI outlets. I realize there must be appropriate supplementary protection but a UL508A testing requirement for ICP installed GFCI outlets?
Anyone heard of this?
