Possible Causes

Water ingress into motor terminal box, Damaged insulation on motor winding, Crushed or cut supply cable, Moisture inside Speck control box

How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a tripping breaker. Risk of fire or electric shock.

Inspection steps:

  • Visually inspect the supply cable from panel to pump for cuts or crushed sections. Replace if damaged.
  • Open the motor terminal box and check for water, corrosion, or loose strands touching the casing. Dry thoroughly and correct wiring.
  • Open the Speck control box (if fitted) and look for moisture or burned components.

Testing:

  • With the pump disconnected, see if the breaker still trips. If not, the fault is in the pump or its wiring.
  • Insulation resistance testing of the motor windings to earth should be performed by a qualified electrician.

Replace the motor if insulation resistance is below acceptable limits.
