Recall 17V320 affects 58 2007-2016 Terex Aerial Devices and Digger Derrick vehicles for shock-risk GFPE breakers. Free repair at franchised Terex dealers.
Terex is recalling 58 2007-2016 Aerial Devices and Digger Derrick vehicles because the GFPE breaker for the onboard electrical socket can fail to trip at the proper current during a tool short circuit. Without that protection, a worker faces greater risk of electrical shock injury, and the Terex dealer repair will be free once available.

What's wrong?
The 2007-2016 Terex Aerial Devices and Digger Derrick vehicles use a Hy-Power electric hybrid battery system when parked for utility line work. That system powers the boom hydraulics and supplies 120-volt power for plugged-in hand tools. A GFCI breaker is supposed to shut off that tool power when electrical current leaks to the wrong path.
On affected vehicles, the installed breaker was built for equipment protection, not personal protection. It trips at 20 mA instead of the expected 6 milliamps, so it does not shut power off soon enough during a short circuit. If a plugged-in tool shorts, the worker using the tool can receive an electrical shock before the breaker opens the circuit.
There is no warning sign before failure. The affected CBi breaker marking is visible through the clear breaker cover, while the replacement Eaton breaker does not show a manufacturer mark without disassembly.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
Without proper electrical shock protection, a user faces a greater risk of injury while operating or working around the equipment. There is no warning sign before an exposure, so stop using the equipment and arrange service if you suspect an electrical issue. Repair will be free at any franchised Terex dealer once available.
What should I do?
- Check your VIN to confirm your 2007-2016 Terex Aerial Devices or Digger Derrick is included in this recall.
- Check your mail for the Terex owner notice sent after June 27, 2017, and follow the repair instructions if your VIN is included.
- Call Terex customer service at 1-800-982-8975 with questions before using the onboard electrical socket for tool work.
- Reference recall number 17V320 when you call Terex or a Terex service location.
- Avoid using tools plugged into the onboard electrical socket until the GFPE breaker replacement is complete, because the original breaker can fail to trip before a shock occurs.
What happens at the repair
Terex has identified the dealer repair: a Terex technician replaces the existing GFPE breakers for the onboard electrical socket with GFCI breakers designed to trip at a lower current. The final dealer repair will be free once Terex opens it for your vehicle. Terex has a general reimbursement plan on file. If you already paid for breaker related work before the recall notice, contact Terex Customer Service Department and ask how to submit documentation under that plan.
