HVAC Disconnect

We recently installed a disconnect for a mini-split HVAC system on a rehabilitation facility in Owenton, Ky. They had a 120/208 volt system, and the HVAC unit needed 2 phases of the 3 phase system. We used the unused 3rd leg to run a weatherproof GFCI out of the disconnect box. This put a convenience outlet within 25 feet of the unit, which is required by the code. The breaker panel covers were held on by sharp lag screws, so we tapped the holes and installed blunt tipped bolts to prevent any possible damage to wires. Unfortunately, this is an issue we see a lot in older panels. The original screws get lost, or the threads get too worn to hold the cover securely. As a result, people will often use any type of fastener they have handy. A sharp tipped screw is a short just waiting to happen. If the screw pokes through the insulation on a wire it can cause a short, which is a fire hazard. Always use blunt tipped fasteners in breaker panels. We appreciate the opportunity to work on a business that helps some of the most vulnerable members of our community, and we look forward to more opportunities in the future.
