Over-Current Protection (OCP) is a feature built in WattBox units to protect your gear and installation from instances of excessive current. Over-Current Protection in the 800 Series WattBox protects from two types of excessive current:

1. Instantaneous Over-Current:  A large in-rush of current at one time, typically experienced when powering up amplifiers.
2. Constant Over-Current:  Continuous current over the unit’s UL rating of 12A.

When Over-Current Protection is triggered, ‘Device Activities’ in OvrC will differentiate between the two.

Ways to Troubleshoot

For Instantaneous OCP:

If a single outlet is off:

• Is the product an amplifier that may have a high in-rush current? If so, remove the amplifier from the IP-controlled WattBox to a surge-only WattBox.

If 3 consecutive outlet groups turn off (1 -3, 4- 6, etc.)

• Set unique power-on delays for the devices with high in-rush current.
• Try rearranging the devices such that they are no longer on 3 consecutive outlets within a group.
• Are these outlets powering amplifiers/AVRs?  If so, we recommend not using an IP-controlled WattBox, instead, use a surge protection-only WattBox. 

For Constant OCP:

• Never daisy chain power strips off WattBox PDUs. The WattBox 800 Series PDUs are UL rated for 12A. Any outlet that sees a current draw higher than 12A will go into protection mode to prevent permanent damage to the PDU and/or to the wiring on-premise.
