Keaten Collinson
Recently a tree fell on the power lines in front of my house and ripped the main service out, I called rewired and they showed up first thing in the morning to begin repairs, Eddie and Frank made quick work of the repair (Replacement Mast and Meter Box) and fixed all the damages, they also worked with MidAmerican to get my service hooked back up as soon as possible! They were very accommodating during the entire process and I would recommend using their services!

Jon was great on the initial visit. Jeremy and Frank knocked it out of the park the day of work. Tough job but both guys were friendly and hard working the entire day. They worked late on a Friday night and made sure all was working before they left. Took time to educate and explain the process. Very fair pricing. Highly recommend

| Breaker Modules | Overcurrent protection, AFCI/GFCI capable | Individual circuits for appliances, tools, and lighting |
| Feeder Wiring | Proper gauge, insulated, separate neutral and ground | Connects main panel to sub panel for safe power distribution |
Differences Between Panel Types and Breakers
Standard sub panels provide extra breaker spaces for additional circuits, while main panels serve as the primary distribution point. Modern breakers add safety features like AFCI/GFCI protection. Rewired Iowa selects panels and breakers based on load requirements, code compliance, and future expansion needs.How Proper Sub Panel Wiring Protects Your Electrical System
Proper sub panel wiring reduces overload risks, separates neutral and ground, and allows safe addition of circuits in the future.

Common Signs You Need a Sub Panel Upgrade
Warning signs of an overloaded or outdated electrical system include frequent breaker trips, flickering lights, burning odors, and visible corrosion. Identifying these issues early helps prevent shocks, fire hazards, and appliance damage.
- Frequent breaker trips: Repeated tripping indicates your circuits are drawing more power than your current sub panel can safely handle.
- Flickering or dimming lights: Voltage fluctuations often signal loose connections or an oversubscribed panel.
- Burning smells or scorch marks: Overheated wires or failing breakers can degrade insulation and create fire risks.
- Outdated or unsafe panels: Older panels may not meet modern safety standards and can fail under current electrical loads.
- Panels older than 25 years: Aging components may no longer comply with NEC requirements and can degrade under heat and load stress.
- New appliances or home expansions: Adding EV chargers, HVAC units, or other high-draw equipment can overload an undersized sub panel.

How Much Does Sub Panel Installation Cost?
Local costs for sub panel installation vary depending on ampacity, materials, labor, and permit fees. A basic 60A garage sub panel typically costs less, while a 100A feeder with a longer run increases the price. Factors affecting cost include feeder conductor type and length, number of breakers, indoor versus outdoor panel, and required inspections. Below is a comparison of common job types with typical amp ratings and estimated price ranges to help homeowners and businesses set expectations.
| Job Type | Typical Amp / Complexity | Estimated Price Range |
|---|---|---|
| Garage sub panel (basic, indoor) | 60A / low complexity | $800 – $1,800 |
| EV charger feed / dedicated circuits | 60A – 100A / moderate | $1,000 – $2,500 |
| Hot tub or spa feed (GFCI required) | 50A / moderate | $900 – $2,200 |
| Complex run to detached building (conduit/long feed) | 60A – 100A / high | $1,800 – $4,500 |
What Factors Influence Sub Panel Installation Cost?
Several variables affect the total price of a sub panel installation. Key cost drivers include the amp rating (60A vs 100A), feeder length and routing, panel and breaker selection, and labor for mounting and wiring. Permit and inspection fees add to the total, and jobs requiring long conduit runs increase both materials and labor. Accessibility to the main panel, replacement of existing equipment, and required safety fixes (bonding/grounding corrections or AFCI/GFCI installs) also affect pricing. For an accurate estimate, schedule a licensed sub panel electrician to evaluate your site.
Typical Price Range for Sub Panel Installation
A straightforward 60A sub panel with a short feed usually falls at the lower end of the range ($800–$1,800). EV charger or hot tub feeds needing 60A–100A typically range from $1,000 to $2,500. More complex jobs — long feeder runs, conduit to detached buildings, or simultaneous main panel work — can exceed $2,500 and reach $4,500 or more depending on materials and labor. Requesting an on-site quote ensures accurate pricing, scope verification, and proper permitting.

FAQ
What is the difference between a sub panel and a main service panel?
A sub panel is a secondary panel that distributes power to specific areas or circuits, while the main service panel is the primary distribution point for the whole building. A sub panel provides localized circuit management and extra breaker spaces without replacing the main service panel.
Can I install a sub panel myself, or do I need a licensed electrician?
While DIY installation is possible, hiring a licensed sub panel electrician ensures compliance with codes, proper load calculations, correct materials, and permits. This reduces the risk of unsafe work or costly rework.
How do I determine the right size for my sub panel?
Selecting the correct sub panel size requires assessing the total load of circuits to be added. Licensed electricians perform load calculations to determine appropriate ampacity. Common residential sizes range from 60A to 100A depending on circuits and future expansion plans.
What types of circuits can be connected to a sub panel?
A sub panel can handle dedicated feeds for EV chargers, hot tubs, workshop tools, plus lighting and outlet circuits for garages or additions. The total load must not exceed the sub panel’s capacity.
Are there any specific permits required for sub panel installation?
Most sub panel installations require permits to ensure NEC compliance. Licensed electricians from Rewired Iowa handle the permit application, scheduling, and inspections for a smooth process.
What are the safety considerations when installing a sub panel?
Safety priorities include neutral-ground separation, correct conductor sizing, and proper overcurrent protection. Installations must meet code requirements and may require AFCI/GFCI protection on certain circuits. Licensed electricians follow all safety protocols and testing procedures.
How can I tell if my existing electrical system can support a sub panel?
Check the load on your main service and available breaker spaces. Signs of overload include frequent trips, flickering lights, or reliance on power strips. A licensed electrician can perform a load calculation and recommend whether a sub panel or main panel upgrade is the right solution.
