    When Your Home Needs Sub Panel Installation

    When Your Home Needs Sub Panel Installation

    Determining whether you need a sub panel installation depends on where you need power and how many circuits are required. Sub panels are ideal when you need multiple circuits in a location away from your main panel, when running individual circuits from your main panel would require excessively long wire runs, or when your main panel lacks space for additional breakers but has adequate amperage capacity.

    Common situations that benefit from sub panel installation include garage workshops requiring circuits for welders, air compressors, and other equipment, detached garages or outbuildings needing lighting, outlets, and EV chargers, home additions requiring dedicated circuits for the new living space, finished basements with multiple circuit requirements, outdoor kitchens and entertainment areas, and pool houses or accessory dwelling units.

    More importantly, attempting DIY sub panel installation creates serious safety risks including electrocution and fire hazards. Sub panel work involves high-amperage connections and must be properly sized and installed to prevent overloading and ensure safe operation.

    Benefits of Sub Panel Installation

    Benefits of Sub Panel Installation

    Sub panel installation offers several advantages over running individual circuits from your main panel. By distributing power locally, sub panels reduce the length of wire runs needed for individual circuits, provide convenient breaker access near the equipment being served, organize your electrical system more efficiently, and allow for easier troubleshooting and maintenance.

    For garages and workshops, having a local sub panel means you can easily add or modify circuits as your needs change without running new wires all the way back to your main panel. This flexibility makes sub panels an excellent investment for spaces where electrical needs may evolve over time.

    Call us anytime at (425) 371-8570 to schedule your free sub panel installation consultation.

    Our Sub Panel Installation Process

    Our sub panel installation process begins with evaluating your electrical needs and your main panel’s capacity to support a sub panel. We assess the circuits you’ll need in the new location, calculate the total load to determine appropriate sub panel sizing, verify your main panel has adequate capacity for the sub panel feeder, and plan the most efficient routing for the feeder cables.

    The installation process involves installing a properly sized breaker in your main panel for the sub panel feeder, running feeder cables from the main panel to the sub panel location, mounting the sub panel in a code-compliant accessible location, connecting the feeder cables with proper grounding, and installing individual circuit breakers and running circuits as needed.

    We install high-quality sub panels from trusted manufacturers, properly sized for your current needs with room for future expansion.

    Garage Sub Panel Installation

    Garage sub panel installation is one of our most requested services, providing dedicated electrical capacity for workshops, EV charging, and general garage electrical needs. A properly sized garage sub panel can support welders and plasma cutters requiring 240-volt circuits, air compressors and dust collection systems, multiple power tool circuits, EV chargers requiring 40-60 amp dedicated circuits, lighting circuits for work areas, and general outlet circuits for convenience.

    We typically recommend 60-100 amp sub panels for garage installations, providing adequate capacity for current needs while allowing room for future additions like a second EV charger or additional equipment

    Sub Panel Installation for Home Additions

    Sub Panel Installation for Home Additions

    Home additions benefit significantly from dedicated sub panel installation rather than running numerous individual circuits from the main panel. A sub panel provides organized, accessible circuit protection specifically for the new living space while simplifying the electrical installation process.

    Sub panels for home additions typically include circuits for bedroom and living area outlets, bathroom circuits with required GFCI protection, kitchen circuits if applicable, lighting circuits throughout the addition, HVAC equipment circuits, and dedicated circuits for any special equipment.

    Planning an addition? Call us anytime at (425) 371-8570 for a free sub panel consultation.

    Detached Structure Sub Panel Installation

    Detached Structure Sub Panel Installation

    Detached garages, workshops, pool houses, and accessory dwelling units all benefit from dedicated sub panel installation. Running power to detached structures requires proper underground or overhead feeder installation along with a sub panel to distribute power within the structure.

    Our detached structure sub panel services include evaluating the electrical needs of the structure, determining appropriate sub panel and feeder sizing, installing underground conduit and feeder cables, mounting and connecting the sub panel, installing individual circuits as needed, and ensuring all work meets code requirements for detached structures.

    Sub Panel Sizing and Capacity

    Sub Panel Sizing and Capacity

    Proper sub panel sizing ensures you have adequate capacity for your current needs while allowing room for future additions. Sub panels are available in various sizes, with common residential options including 30-amp sub panels for light-duty applications with just a few circuits, 60-amp sub panels suitable for most garage and workshop applications, 100-amp sub panels for larger workshops or home additions with significant electrical needs, and 125-amp or larger sub panels for accessory dwelling units or structures with extensive requirements.

    We help you select the right sub panel size based on your planned circuits, potential future needs, and your main panel’s available capacity. Choosing a slightly larger sub panel than your immediate needs often proves cost-effective by avoiding future upgrades.

    Sub Panel Installation Code Requirements

    Sub panel installation must comply with electrical codes that ensure safe operation and proper protection. Key code requirements include proper feeder sizing based on sub panel amperage, correct grounding and bonding at the sub panel, required working clearances around the sub panel, appropriate wire types and installation methods for feeder cables, and AFCI and GFCI protection where required by current codes.

    We ensure all sub panel installations meet current code requirements and pass required inspections, protecting you from safety hazards and future complications.

    Sub Panel Installation Permits and Inspections

    Sub panel installation requires permits and inspections in all jurisdictions throughout Snohomish and King Counties. These requirements ensure the work meets safety standards and protect homeowners from dangerous installations.

    We handle all permitting and inspection requirements for your sub panel installation, including preparing and submitting permit applications, scheduling inspections at appropriate milestones, addressing any inspector comments or corrections, and providing documentation of your approved installation

    Excellent support from REddie! Had a mysterious electrical issue with 5 receptacles in a 48 year old home that has had multiple projects. Timely response, extensive troubleshooting resources spent identifying a rather obscure location for a loose neutral. Vadim & Yasir were friendly, professional and highly effective. Identified and Updated some code issues in the process.

    Eddie was an absolute pleasure to work with. Due to a scheduling mix-up, I found myself in a real bind, with other workers scheduled for the following day who couldn’t do their jobs until I had electricity run above my fireplace. Eddie went out of his way to rearrange his schedule and somehow managed to get someone to my house within just a couple of hours. The electrician he sent—I wish I could remember his name—did an excellent job. He asked lots of questions to make sure everything was done exactly the way I wanted it, carefully measured and double-checked the placement before drilling, and the finished work looks beautiful. He also cleaned everything up thoroughly before he left. I really appreciated Eddie going above and beyond to help me out on very short notice. Great service, excellent workmanship, and a company I would definitely use again.

    I found REddie Electric on a Google search looking to update all 9 of the hardwired smoke detectors in my home. Communication has been exceptional, I have been able to text with questions and requests, and received prompt responses, this quality of communication is really important in my world! I received a quote quickly for installation of 9 hardwired “smart” detectors, and was required to pay a 30% deposit to schedule. Yasir arrived on time, was professional, and did an excellent job with installation, testing and clean up. Wonderful attention to detail and was kind enough to greet all my cats and allow them to “help out”. He connected all detectors to my WiFi and Ring app. I really appreciate the ability to be notified of alarms when I am away from my home, and to be able to turn them off without having to push the physical button. I highly recommend REddie Electric, and will use them in the future for other services they offer.

    Eddie was wonderful working with for booking our recess lighting project. He gave us an upfront quote, was very responsive and didn't mind me asking a ton of questions. He answered every single one of my questions and I decided to book his company. Yasir worked on our home project and was polite, attentive and did a great job. We had 8 recess lights installed in our living room. Would highly recommend Reddie Electric!

    Reddie Electric is the best. They are one of the few that handle 24 hour electrical issues. I had a power failure and it was 12am and Eddie was out there at 1am and worked until it was fixed. I use him for all of my electrical needs.

    Found Reddie Electric on the web via Google. Had a problem with a single outlet that we couldn't figure out. They came and fixed it. Thru conversation I realized that I wanted to fix the issues from our inspection from when we bought this house a few years ago. Discussed it with Eddie, the price was doable, time frame was fairly quick considering he had to set up with PUD to cut power and the county to have an inspection. Eddie & Yasir replaced our breaker box, changed 8 outlets to gfci, both inside and outside & added 2 junction boxes in the attic for wires that were just laying on the insulation. Very happy with the results, everything looks good, everything works. We now have peace of mind now that our electrical is in good shape. Eddie always took the time to answer my questions and listen to me. Pics show new stuff. You can see in the 3rd picture a hole in the wall on the right one of the previous owners had put an outlet there connecting it straight to the breaker box which would not have been code. They put a new outlet in for us down below. Overall, I would hire Reddie Electric again and recommend him.

    I'm new to the Area and Found REddie Electric LLC on Google. Submitted them a request to install a 240v outlet in the garage in order to have an EV car charger. They responded back super quick and gave me a solid fair quote for the work. I gave them a call and Eddie told me he'd be out the next morning. Super transparent communication. Pricing is great, and the work was done in a very timely manner. Eddie has a great work ethic and professional outlook on the jobs he takes. I'll definitely be back for more jobs.

    Eddie is an absolute rock star! If you need an electrician, look no further, this guy is a wizard when it comes to installing backup generators. From start to finish, Eddie was fast, efficient, and incredibly knowledgeable. Not only did he get the job done flawlessly, but he also went above and beyond to ensure everything was safe and up to code. If you want someone who's professional, skilled, and genuinely cares about their work, Eddie is your guy. I can't recommend him enough.
