When Michigan requires the exterior disconnect
Michigan's current Part 8 rules add Section 230.85 requirements for one- and two-family dwellings and state that they apply where service equipment is replaced. The Michigan rule also contains an exception when only meter sockets, service-entrance conductors, or related raceways and fittings are replaced.
Because the trigger depends on the project scope and service arrangement, Landmark confirms the applicable requirement with the local authority before finalizing the installation.
The disconnect changes grounding and bonding decisions
When the exterior equipment becomes the service disconnect, the neutral-ground bonding point and the conductors supplying the interior panel must be arranged accordingly. The interior panel generally becomes downstream equipment with separated neutral and equipment-ground paths.
Landmark coordinates the disconnect rating, available fault-current rating, service conductors, grounding electrode conductor, surge protection, labeling and downstream panel changes as one design.
What the installation plan identifies
The proposal states whether the disconnect is part of a complete service replacement or a defined update, the equipment rating and location, utility and permit sequence, required markings, other-source directory needs and the related panel or grounding work included.
- Readily accessible outdoor location on or within sight of the dwelling
- Service-disconnect rating and suitability for the installation
- Required emergency-service-disconnect marking
- Identification of other energy-source isolation equipment when applicable
- Coordination with surge protection, grounding, bonding and downstream panel configuration
Codes and standards that apply
These references explain the framework for this work. The adopted code, Michigan amendments, local authority, utility rules, equipment listings and manufacturer instructions must be considered together for the actual installation.
Frequently asked questions
Does every existing Michigan home need an exterior emergency disconnect now?
The current Michigan rule applies the requirement to defined service work, including service-equipment replacement, and includes a limited exception for certain component-only replacements. The actual project scope and local enforcement determine applicability.
Is an emergency disconnect the same as an HVAC or hot-tub disconnect?
No. A dwelling emergency service disconnect controls the building service. Equipment disconnects serve specific appliances or systems and belong within those project requirements.
Will the interior main panel need to change?
It may. When the service disconnect moves outside, bonding, conductor and interior-panel arrangements must match the new service configuration. Landmark includes the required downstream changes in the project plan.

What your service visit includes
Your $79 dispatch and evaluation charge covers sending an electrical professional to your property and the initial on-site evaluation. During that evaluation, the electrician examines the relevant accessible system, shows or explains the supported findings and identifies the cause when the available evidence reasonably allows. Clear, flat-rate options are presented before approved work begins, and the charge is waived when you proceed with approved work during the visit. Any special access, extended diagnosis, permit or after-hours considerations are explained before work moves forward.
