Okay, this is a common challenge. You're right to think ahead about the brick standoff. Here's a breakdown of how to approach this, incorporating best practices and addressing the issues you've raised

Understanding the Problem:
Standoff

You need to create a solid, weatherproof standoff of 4.5" from the sheathing for the meter base and disconnects. This standoff needs to be strong enough to support the weight and any potential stresses (weather, service cable tension).

Flush Mount

You want the front of the meter base and disconnects to be flush with the finished brick surface. This provides a clean, professional look.

Weatherproofing

This is outside, so EVERYTHING needs to be weathertight to prevent water damage and potential electrical hazards.

Code Compliance

Absolutely critical. Your installation must meet local electrical codes. This includes working space clearances and proper grounding.

Solutions and Recommendations

Here's the most common and effective approach, building upon your 2x4 frame idea, but with some key improvements:1.

The Frame (Key to Success)



Material

Use pressure-treated lumber for the frame. This is crucial for longevity and to resist rot from moisture that will inevitably get behind the brick. 2x6 is better than 2x4, use 2x6

Construction

Build a rectangular frame that is slightly larger than the footprint of your meter base and the combined footprint of your two disconnects. You need room to attach the frame securely to the wall.

Depth

The critical part. Your frame needs to be 4.5" deep (or very slightly more, depending on the lip of your meter/disconnects).

Corners

Strong, well-constructed corners are vital. Use screws rated for exterior use for the frame.

Mounting

Make sure you have plenty of room to attach it to the wall securely.

Plywood Sheathing (Front of Frame)

Use exterior-grade plywood (like ACX or BCX) at least 3/4" thick. Cut this plywood to match the outer dimensions of the frame. This will be the "face" that the meter base and disconnects mount to. Attach the plywood to the frame securely with exterior-grade screws.2.

Attachment to the Wall



Location

Carefully plan the location, considering the service drop location, conduit runs, and clearances.

Fasteners

Use heavy-duty lag screws or structural screws of appropriate length to penetrate the sheathing AND go into the wall studs. Don't rely on just the sheathing for support.

Spacing

Space the screws adequately (e.g., every 12-16 inches) to distribute the load evenly.

Weatherproofing

Before attaching the frame, apply a generous bead of high-quality exterior caulk (silicone or polyurethane) to the back of the frame where it will contact the sheathing. This seals against water intrusion.3.

Mounting the Meter Base and Disconnects



Pilot Holes

Drill pilot holes through the plywood for the mounting screws for the meter base and disconnects.

Hardware

Use stainless steel screws or bolts to mount the meter base and disconnects.

Grounding

Pay extremely close attention to grounding. The meter base and disconnects must be properly grounded. Refer to your local codes for the correct grounding methods.

Wiring

Make sure you have sufficient wiring to make all connections comfortably.4.

Weatherproofing (Critical)



Caulk

Apply caulk around the perimeter of the meter base and disconnects where they meet the plywood.

Drip Loop

Ensure your service cable has a proper drip loop to prevent water from running down the cable and into the meter base.

Conduit Seals

Use proper sealing fittings where conduits enter the meter base and disconnects to prevent water ingress.5.

Coordination with the Brick Mason



Clear Communication

Talk to the brick mason about the finished location. They need to know that the meter and disconnects must be flush with the brick surface.

Potential for Adjustments

There is always a small chance of variation, so I would make the box slightly deeper so you have options to shave down if needed.

Important Considerations



Local Codes

I cannot stress this enough. Contact your local building department and electrical inspector before you start. They can provide specific requirements and may have preferred methods for mounting electrical equipment on brick walls.

Service Cable Size

Ensure the service cable is adequately sized for the load.

Working Space

Maintain the required working space clearances around the meter and disconnects (typically 3 feet in front and adequate side space). This is a code requirement.

Electrical Safety

If you are not a qualified electrician, do not attempt this work. Electrical work can be dangerous and requires specialized knowledge and skills.

Overhang

You might consider adding a small roof or overhang to protect the meter and disconnects from direct rain and sun.

Why This Approach is Best



Solid Support

The frame provides a stable and strong base for the meter base and disconnects.

Weatherproof

The use of pressure-treated lumber, exterior plywood, and proper caulking creates a weatherproof installation.

Flush Mount

It allows you to achieve the desired flush-mount look with the brick.

Code Compliant

It allows you to meet code requirements for grounding, working space, and weatherproofing.

In Summary:

Don't take shortcuts on this. A well-built and properly installed mounting system will ensure the longevity and safety of your electrical service. Consult with your local inspector, follow the steps outlined above, and prioritize quality materials and workmanship. If you are not 100% comfortable with any aspect of this, hire a qualified electrician. Flag for review
