Current carrying connection bolts
With proper conductor cross-section and proper terminal ends (the contact surfaces must be commensurate) you can use the terminal-bolt for the following current rating.
Current-carrying capacity for terminal -bolt*
| Ampere | Thread |
|---|---|
| 35 | M4 |
| 75 | M5 |
| 125 | M6 |
| 150 | M8 |
| 200 | M10 |
| 350 | M12 |
| 500 | M16 |
* Bolt is not leading current
Terminal-bolts from materials like aluminium or copper are not admitted.

For the connection torque specification of the terminal boards we can`t give any information, because we don`t know the state of the seat.
