Hey esk1020,
WEN DC1300 has a product manual, where it says:
| Model number | DC1300 |
| Motor | 120V, 60 Hz, 14A |
| Motor Speed | 3450 RPM |
| Impeller Diameter | 10 Inches (254mm) |
| Inlet Hole Diameter | 5 Inches |
| Inlet Y-Adapter Hole Diameter | 4 Inches |
| Air Suction Capacity | 1,300 CFM |
| Collection Bag Capacity | 50 Gallons |
| Filter Bag Rating | 5 Microns |
| Assembled Dimensions | 33.5 in. x 22 in. x 73.2 in. |

Generally I would say the max. Ampère rating for a relay means the max. current you can safely draw. That’s the disadvantage of 120 V voltage, with 230 V it would only be half the current.
I think this socket is more for shop vacs and less for serious dust collection systems like the WEN.
