This is similar to breaker and relay testing already offered by manufacturer's service divisions and independent testing companies.How are people dealing with 240.87C, Arc-reduction performance testing after installation? Are the manufacturers doing it, or third-party contractors? It seems like a significant new cost to contractors.

Yes, manufacturers compete with local testing companies and often work on other manufacturers equipment, especially if it is old.I did not realize manufacturer's service divisions regularly test equipment. I've only seen them called in for unusual circumstance, like water or other damage, to test and recertify equipment. Do they charge for this? It can't be easy to test an arc-reduction method, when the change is in milliseconds.
