Electrical guides and planning resources
Each completed guide gives a direct answer, explains key distinctions, identifies warning signs, outlines Landmark's field approach, links to relevant services and cites current official sources. The Project Gallery remains outside search results until first-party project photographs and details can support it.
Electrical Codes, Standards & Safety Resources
This master resource explains which electrical rules and instructions may govern work in a Metro Detroit home, where customers can review official sources, and how Landmark keeps service-page references current without reproducing copyrighted code text.
Open resourceGrounding vs. Bonding: A Michigan Homeowner Guide
Grounding and bonding are often spoken about as if they were one thing. They work together, but they solve different electrical safety problems. This guide helps Michigan homeowners understand the difference and recognize when a professional evaluation is appropriate.
Open resourceGFCI vs. AFCI Protection
GFCI and AFCI protection address different electrical hazards. A GFCI responds to current leaving its intended path, while an AFCI responds to electrical signatures associated with dangerous arcing; some locations and projects require both forms of protection.
Open resourceWhole-Home Surge Protection Guide
Whole-home surge protection limits transient overvoltage before it spreads through a home's electrical system. It supports layered protection, but it cannot correct sustained voltage problems, defective wiring or every direct lightning event.
Open resourceElectrical Panels & Service Equipment Guide
The electrical service brings utility power to the property, and the panel distributes that power through protected circuits. A safe upgrade requires more than a larger box: it must address load, equipment condition, service rating, grounding, bonding, surge protection, permits and utility coordination.
Open resourcePool, Spa & Hot-Tub Electrical Safety
Pools, spas and hot tubs require coordinated protection against shock in wet environments. The electrical plan must address circuits, GFCI protection, disconnects, equipment location, wiring methods and specialized equipotential bonding around the actual installation.
Open resourceGenerator Connections & Transfer Equipment Safety
A generator must connect through approved transfer equipment that prevents utility and generator sources from energizing the system at the same time. Safe planning also requires load management, correct neutral and grounding treatment, proper outdoor operation and manufacturer-specific installation.
Open resourceEV Charger Readiness & Load Management
EV-charger readiness means matching the driver's charging needs to the home's service capacity, panel, wiring route and selected equipment. The best solution may use a full-output circuit, a lower configured output or supported load management rather than an unnecessary service upgrade.
Open resourceElectrical Inspection Guide for Home Buyers & Sellers
A transaction-focused electrical inspection helps buyers and sellers understand accessible electrical condition, capacity and repair priorities before closing. It does not replace a whole-home inspection, municipal approval or a guarantee about concealed wiring.
Open resourceMichigan Electrical Permits & Inspections
Michigan electrical projects follow the currently adopted code, state amendments and the permit and inspection process administered by the authority with jurisdiction. The municipality and actual scope determine whether a permit, plan review, registration, inspection or utility release applies.

Open resourceUse information without turning it into a diagnosis
Electrical systems change from one property to the next. Use these guides to identify the right questions and service path, then rely on the adopted code, local authority, utility requirements, equipment instructions and field findings for the actual scope.
- Do not remove panel covers or touch exposed energized parts
- Stop using equipment that shows heat, arcing, smoke or severe damage
- Call 911 for fire, heavy smoke, injury or immediate danger
- Use current official program and code sources instead of saved screenshots or old summaries
Knowledge Center FAQs
Does Landmark's Knowledge Center replace an electrical inspection?
No. These guides help customers understand terms, hazards and planning decisions. Field conditions, measurements, adopted requirements and equipment instructions determine the actual project.
Which code applies to electrical work in Michigan?
Michigan LARA identifies the currently adopted code and Part 8 rules. The local authority, residential requirements, utility standards and project scope also affect the final determination.
Can I use these guides to perform my own repair?
The guides support safe recognition and better questions; they do not provide energized-work instructions. Use a licensed electrical contractor for diagnosis and permanent work.
