Complete Well Pump Electrical — Panel Installation, Repair & Emergency Response
Irrigation, domestic, and livestock well pump electrical across Twin Falls County and Magic Valley. We understand Magic Valley irrigation depths and the motor loads that come with pumping from Snake River Plain aquifer depths.
3-Phase Well Pump Panel Installation
3-phase pump panel installation for irrigation and high-volume agricultural well pumps. Sized from 10HP to 500HP motor loads. MVEC and Idaho Power service coordination included. We’ve installed 3-phase pump panels from Shoshone Road South to the Jerome County line.
Submersible Pump Wiring
Electrical wiring for submersible pump installations — from the panel to the pump motor in the well casing. Proper wire sizing for pump depth, sealed splice kits at the water level, and pump protection devices. We work with pump contractors across Magic Valley.
Soft-Start & VFD Installation
Soft-start motor controllers and variable frequency drives (VFDs) for well pumps with hard-start issues — high inrush current, frequent fuse failures, and motor wear from direct-on-line starting. Properly sized for your motor HP and pump load.
Pressure Switch & Control Wiring
Pressure switch installation, tank wiring, and control circuit installation for domestic and livestock water systems. We wire the complete control system — from pressure switch to pump panel — for a reliable, code-compliant installation.
Pump Panel Troubleshooting & Repair
Pump won’t start? Trips the breaker? Runs continuously without pressure? We diagnose and repair pump panel faults — blown fuses, failed contactors, tripped overloads, and control circuit failures — fast. Bring parts in the truck to minimize downtime.
24/7 Emergency Well Pump Response
Domestic well with no water? Irrigation pump down at the start of a set? We dispatch pump emergency calls immediately around the clock. Agricultural pump failures go to the front of our dispatch queue.
Magic Valley Well Pump Electrical Requires Specific Expertise
Pumping water from the Snake River Plain aquifer in Twin Falls County involves depths that determine wire sizing, pump HP requirements, and startup load characteristics. A 400-foot deep irrigation well running a 75HP pump at full load is a very different electrical job from a 150-foot domestic well with a 5HP pump. We size pump panels, wire gauges, and protection equipment correctly for your specific depth and motor nameplate data.
We also understand the difference between Idaho Power and MVEC service requirements for pump panels. MVEC has different metering and service extension processes than Idaho Power — and we work with both utilities’ processes every week across Magic Valley.
- Wire sizing based on pump depth and motor nameplate — not guesswork
- MVEC and Idaho Power both coordinated for service work
- Soft-start and VFD sizing for your specific motor and pump curve
- 24/7 emergency response — pump down is a priority call
- Idaho DOPL licensed on every job

Frequently Asked Questions — Well Pump Electrical in Twin Falls, Idaho
My well pump won’t start — what should I check before calling?
Check the pressure switch — make sure it’s not stuck in the open position and the contacts are clean. Check the panel breaker — reset it if it’s tripped. If it trips immediately on reset, there’s a fault and you need to call us. Check that you have power at the panel. If everything looks normal but the pump still won’t start, call (208) 719-5016 — we’ll triage over the phone and dispatch if needed.
What size pump panel do I need for an irrigation well in Twin Falls County?
Irrigation pump panel sizing depends on your pump motor HP and the utility voltage available at your location. A 50HP motor at 480V 3-phase requires approximately a 100A service at the panel. A 100HP motor requires 200A. We do a load calculation during the estimate based on your motor nameplate data — don’t size a pump panel by guessing.
Do you coordinate with MVEC for well pump panel work in Jerome and Gooding County?
Yes. Many Twin Falls County border areas and all of Jerome and Gooding counties are in MVEC territory. We coordinate with MVEC for service extensions, 3-phase additions, and meter base work the same way we work with Idaho Power. We know MVEC’s application process and timelines.
Why does my irrigation pump blow fuses at start-up?
Blown fuses at pump start-up are usually caused by high inrush current during direct-on-line starting — often 6–8 times full-load current on the first rotation. Solutions include time-delay fuses (sized correctly for your motor), a soft-start motor controller, or a VFD. We diagnose the root cause and recommend the right fix — not just upsizing the fuse, which creates a fire hazard.
