BATTERY DOCTOR
Frequently asked questions
Common questions about BATTERY DOCTOR from 3G Electric.
What are the voltage and temperature ratings for BATTERY DOCTOR GPT primary wires?
BATTERY DOCTOR GPT primary wires are rated for 60 V and are constructed with PVC insulation. The operating temperature range for GPT wire is typically -40°C to 105°C, suitable for engine compartments and general automotive wiring. The insulation is resistant to oil, gasoline, and abrasion, meeting SAE J1128 standards for low-voltage primary wire.
How do BATTERY DOCTOR 31200 Series circuit breakers reset after a trip?
The 31200 Series circuit breakers are manually resettable. After a fault causes the breaker to trip, the internal mechanism opens the circuit. To reset, press the button on the breaker once the fault is cleared. This design allows for repeated use without replacement, unlike fuses. The breakers are rated for 42V DC and have interrupt ratings of 100 A or 180 A at 12V DC.
Can BATTERY DOCTOR primary wires be used in marine environments?
BATTERY DOCTOR GPT primary wires are primarily designed for automotive use, but their PVC insulation provides resistance to moisture and salt spray, making them suitable for some marine applications. However, for direct exposure to bilge water or high-humidity areas, consider using tinned copper or marine-grade wire. Always verify local marine regulations for wiring standards.
What is the difference between BATTERY DOCTOR 20 AWG and 22 AWG primary wires?
The primary difference is current-carrying capacity. 20 AWG wire can handle up to approximately 11 A for power transmission, while 22 AWG is rated for about 7 A. Both are rated for 60 V and come in 100-foot spools. Choose 20 AWG for higher current loads like lighting circuits or accessories, and 22 AWG for signal or low-power connections.
Are BATTERY DOCTOR circuit breakers compatible with standard automotive fuse panels?
No, BATTERY DOCTOR 31200 Series circuit breakers use stud terminals, not blade or glass fuse form factors. They are designed for direct mounting to a panel or battery terminal using a nut and bolt. They are not drop-in replacements for standard fuse holders. Use them in applications where a resettable, heavy-duty overcurrent protection device is needed.
