About NEMA 5-20P 20A 125V Plug Adapter Blocks
The NEMA 5-20P adapter block will allow you to access power from a standard 20 Amp power source in North America (5-20R) and adapt the configuration to a specific outlet type that will mate with your equipment's power supply cord. If your power source is a NEMA 5-20R and your plug will not mate with it, this is the product line you are looking for.
