Okay, let's break down your situation and the best approach for connecting your generator to your setup, keeping in mind safety and code compliance.

Understanding the Situation Existing Setup

You have a 200A service to the detached garage (containing a 200A panel). This feeds the house via a 50-foot run to another 200A panel. The PUD removed the house's meter and spliced the house feeder into the main garage meter can.

Generator Goal

You want to connect a 28kW generator to back up both the garage and the house.

Key Question

Where is the best (safest, most code-compliant) place to make the generator connection?

Analysis and Options

Let's analyze the options you've presented, and some other alternatives, with their pros and cons:1. Splice in the Meter Can



Pros

Could seem simpler initially (just splice into the existing service conductors).

Cons (Significant Problems)



Highly discouraged

Messing with service entrance conductors in the meter can is often heavily restricted. The PUD typically owns that portion of the service. You absolutely need their permission before doing anything.

Overcurrent Protection

The meter can does not have overcurrent protection for the generator. If the generator overloads, there is no breaker to trip. This poses a fire hazard.

Safety

Working in a live meter can is extremely dangerous.

Code Violations

Almost certainly violates local electrical codes and PUD regulations.

Generator Connection Type

This doesn't facilitate a proper transfer switch connection. You need a way to isolate the generator from the utility and prevent backfeeding.

Verdict



Do NOT do this without explicit, written approval from your PUD. It's likely they will prohibit it.2. Use the Garage Panel as the Splice Point / Transfer Switch Location



Pros



More manageable

You're working downstream of the service entrance (after the main breaker in the garage panel), which is generally safer.

Overcurrent Protection

The garage panel has overcurrent protection, which is essential.

Space

Panels can usually accommodate a proper transfer switch setup.

Cons



Load Considerations

Ensure the garage panel can handle the combined load of the garage plus the house. You might need to adjust breakers to prevent overloading.

Distance

50-foot run to the house adds a voltage drop consideration.

Verdict



The best option, but requires careful planning and execution.3. Install a Subpanel for Generator Connection in the Garage (near the Main Panel)



Pros



Dedicated Connection Point

Provides a clear, separate location for the generator interface.

Easier Load Management

You can decide exactly what loads the generator will power by choosing which circuits to move to the subpanel.

Less Clutter

Keeps the main panel cleaner.

Cons



Additional Cost

Requires purchasing and installing a subpanel.

More Work

Requires re-routing some circuits.

Verdict



Excellent option, providing a clean and organized setup. Often preferred by experienced electricians.4. Install a Transfer Switch at the House Panel



Pros



Direct Backup for the House

Provides a simpler backup solution for the house itself.

Cons



Longer Generator Cable Run

Requires a 50-foot (or longer) generator cable run, which can be expensive and create voltage drop issues. Also needs to be protected.

Doesn't Backup the Garage

The garage loads would not be backed up.

Verdict

Less desirable unless you only want to backup the house.

Recommended Approach (Detailed)

Here's a refined recommendation based on the above analysis:1. Consult with a Licensed Electrician



This is crucial! They can assess your specific situation, local codes, PUD requirements, and generator specifications to determine the safest and most compliant solution. Get at least 2-3 quotes.2. Contact Your PUD

Discuss your plans with the PUD. They will have specific requirements regarding generator connections and may need to inspect the installation. Do not proceed without their approval, especially if you are considering any work in the meter can.3.

Choose a Transfer Switch

Select a properly sized manual or automatic transfer switch. The size will depend on the amperage and number of circuits you want to back up.

Automatic Transfer Switch (ATS)

Automatically switches to generator power when the utility fails. More expensive, but provides seamless backup.

Manual Transfer Switch

Requires you to manually switch between utility and generator power. Less expensive.4.

Determine the Connection Point



Option A (Recommended): Install a subpanel in the garage next to the existing 200A panel specifically for the generator. Wire the transfer switch to this subpanel. Move essential circuits from the garage and the house panels to the subpanel. This allows you to manage the generator's load effectively. Option B (If Subpanel is Not Feasible): Use the existing 200A garage panel. Install the transfer switch there. This is viable if you have enough space and breaker capacity. You'll need to carefully calculate the loads on the garage panel and possibly rearrange circuits.5. Wiring



Generator Connection

Use appropriately sized wiring (determined by the generator's output and distance) to connect the generator to the transfer switch. Ensure the wiring is suitable for outdoor use if the generator is outside.

Transfer Switch to Panel

Connect the transfer switch to the chosen panel (either the garage panel or the subpanel) according to the manufacturer's instructions.

Grounding

Ensure proper grounding of the generator, transfer switch, and all panels.

Important Considerations Load Calculation

Perform a thorough load calculation to determine the total amperage draw of the circuits you want to back up. This will ensure the generator and transfer switch are adequately sized. You can do this yourself, but an electrician can help ensure it's accurate.

Voltage Drop

The 50-foot run to the house panel could cause voltage drop, especially under heavy load. The electrician can calculate this and recommend appropriately sized wiring to minimize it.

Permits

Obtain any necessary permits from your local building department before starting the work.

Safety First

Turn off the main breaker before working on any electrical panel. Wear appropriate safety gear (insulated gloves, safety glasses). If you are not comfortable working with electricity, hire a qualified electrician.

Summary

While splicing into the meter can might seem like a quick solution, it's likely prohibited and highly discouraged due to safety and code concerns. The best approach is to work within the garage panel (or install a subpanel there) for a safe, code-compliant, and manageable generator connection. Always consult with a licensed electrician and your PUD before starting any work. They can provide specific guidance based on your local regulations and your specific electrical setup. Flag for review
