Okay, let's break down your proposal for adding a generator interlock and more circuits to your mobile home while minimizing interaction with the power company (POCO).

Analysis of Your Plan



Feasibility & General Concept

Yes, conceptually, this is a workable solution. The goal is to extend your electrical capacity and add a generator connection without touching the main service entrance.

Code Compliance (Red Flag Area)

This is where things get tricky and depend heavily on local codes, the age of the mobile home, and the specific equipment you plan to use. What might have been acceptable 40 years ago almost certainly isn't now.

You ABSOLUTELY MUST consult with a licensed electrician and local building inspector BEFORE starting any work. This cannot be emphasized enough.

Here's a more detailed breakdown of potential issues and considerations


Meter Pedestal & Service Capacity



Is the 200A Service Truly Adequate? Even though you have a 200A service, double-check that the actual calculated load of the mobile home (including existing appliances, potential future loads, and the added circuits) doesn't exceed 80% of the service rating. Overloading can lead to dangerous situations. Pedestal Integrity

Make sure the existing meter pedestal and its grounding system are in good condition. Corrosion or damage needs to be addressed.2.

Feed-Through Panel



Suitability

A 200A feed-through panel is a reasonable choice. Make sure it is rated for outdoor use (NEMA 3R or similar).

Location

You mentioned mounting on the outside of the mobile home.

NEC Requirements

The National Electrical Code (NEC) and local codes have specific requirements for mounting panels on buildings. Consider clearances (from ground, windows, doors), protection from physical damage, and accessibility for service.

Mobile Home Construction

Mounting to a mobile home can be tricky. You need to ensure solid attachment to the frame or other structurally sound members. Penetrations for wiring must be properly sealed to prevent water and rodent intrusion.

Feed-Through Lugs

Carefully select the correct size and type of conductors and lugs for the feed-through connections. Torque all connections to the manufacturer's specifications.3.

Running Feed from Meter to New Panel



Conduit & Wiring

You'll need to use appropriate conduit (likely rigid or PVC, depending on local codes) and wire type (likely THHN/THWN in conduit) for this run. The wire size must be rated for 200A and the distance of the run (voltage drop considerations).

Burial Depth (If Applicable)

If the conduit is buried, there are minimum burial depth requirements based on the voltage and type of wiring.

Disconnect

Depending on the distance between the meter and the new panel, you might need a disconnect at the new panel. This is code-dependent.4.

Refeeding the Mobile Home



Existing Feeder

You'll be disconnecting the existing feeder from the meter pedestal and connecting it to the new feed-through panel. Inspect this feeder carefully for damage or degradation. If it's old or undersized, consider replacing it.

Main Breaker

Ensure the mobile home's main breaker (presumably in its internal panel) is properly sized to protect the feeder.5.

Generator Interlock & Inlet



Interlock Kit

Use a listed interlock kit specifically designed for the brand and model of the panel you choose. Do NOT try to create a homemade interlock.

Generator Inlet

The generator inlet (the plug where you connect the generator) needs to be appropriately sized for the generator you plan to use (amperage and voltage). Typically this will be a 30 amp or 50 amp inlet.

Wiring

The wiring from the generator inlet to the interlock should be sized to match the inlet's amperage rating.6.

Grounding



Essential! Proper grounding is critical for safety. You need to ensure the new panel is correctly bonded and grounded. This involves a grounding electrode system (ground rod(s), water pipe ground, etc.) and bonding all metallic parts of the panel and conduit. Mobile Home Grounding

Mobile homes have specific grounding requirements, often involving the frame of the home. Consult the NEC and local codes for details.7.

Permitting and Inspection



Mandatory! You must obtain the necessary permits from your local building department before starting any work. They will inspect the installation to ensure it meets code. This is for your safety and the safety of others.

Key Considerations & Warnings



Aluminum Wiring

If your mobile home has aluminum wiring (common in older mobile homes), you need to be extremely careful and use only connectors and devices specifically rated for use with aluminum. Consider having a qualified electrician inspect and potentially replace the aluminum wiring with copper.

Mobile Home Electrical Systems

Mobile homes have unique electrical systems, often with tighter spaces and specific requirements.

Backfeeding

Ensure the interlock system absolutely prevents backfeeding power onto the utility grid. Backfeeding is extremely dangerous to utility workers and can damage equipment.

Amperage Calculation

It is recommended that you hire a licensed electrician to perform an amperage calculation for the mobile home to ensure the existing service and the addition of the new circuits do not exceed the rating of the service equipment.

Recommendation


Hire a Licensed Electrician

Seriously. This is not a project for someone who hasn't worked on mobile home services recently and isn't fully up-to-date on the NEC and local codes.2.

Consult with the Local Building Department

Discuss your plans with the building inspector before you hire the electrician. They can provide valuable insights into local requirements.3.

Comprehensive Plan: Work with the electrician to develop a detailed plan that includes: Load calculation Wiring diagram Equipment specifications Grounding planBy following these steps, you can ensure a safe and code-compliant installation that meets your needs. Trying to cut corners or skip the proper permitting process can lead to dangerous and costly problems down the road. Good luck! Flag for review
