The terminal block used in the H1000 is spec’d to 12 AWG and our Engineering department tested with 12 AWG wire as well. It can certainly be tight fit, but often times screw terminals are designed that way to ensure no over cabling.
Here is an easy guide for installing this device:
- Trim the insulation of the wire to about ¼”
- Insert the wire into the terminal block
- DO NOT TWIST THE COPPER WIRE as it will be much more difficult to insert
