"The adapter I bought from Steambrite supply was exactly what we needed to run a concrete grinder without the use of out generator, like we had used in the past. Now, job sites are much quieter, and we’re able to work in environments with no airflow like a basements, without the worry of carbon monoxide. It worked exactly as described, and is well built. My electrician neighbor was impressed with it too when it arrived. Its not cheap but you get what you pay for” Thanks, Shaun Owner Closet Envy Inc. https://www.closetenvy.ca/
