Question: I have not visited a site and was given some preliminary info, and trying to identify what kind of switch this is in the photo of a 200A service as seen from Google maps street view. It looks like an enclosed breaker or a Safety switch, any idea if it is something else, such as an outdoor loadcenter that might have branch breaker positions in it?Photo is a bit fuzzy.
Okay, I understand the situation. Let's analyze what it likely is, given the information and the typical installations for a 200A service.Here's a breakdown of the possibilities, ranked by probability, and how to distinguish them (even with a fuzzy photo)
Most Likely Scenarios:
1. Enclosed Service-Entrance Rated Disconnect Switch (Safety Switch)
This is the most probable scenario for a 200A service disconnect viewed from the exterior.
Why it's likely
Disconnect switches are often required for easy access for first responders. They also provide a way to kill power to the entire premises quickly during maintenance or emergencies. They're usually installed outdoors for accessibility.
What to look for (even with fuzziness)
Heavy-duty, NEMA-rated enclosure
Designed for outdoor use (rainproof, corrosion-resistant).
Handle/lever
A prominent, visible handle that operates the switch. The handle will likely have a way to lock it in the "off" position.
Clear markings
Labels indicating "Service Disconnect," "Main Disconnect," amperage rating (200A), and voltage.2.
Enclosed Circuit Breaker (Service Rated)
This is also a possibility, especially if the local code allows it.
Why it's possible
Circuit breakers can act as a service disconnect. An enclosed breaker is weather resistant.
What to look for
Similar to Safety Switch
A heavy-duty, NEMA-rated enclosure.
Breaker Handle
A distinct breaker handle (though often enclosed behind a small door/cover).
Trip Indication
An indication if the breaker has tripped (usually a red flag or marked position).
Markings
Service Disconnect, Main Breaker, amperage, voltage, and interrupting rating (important for safety).
Less Likely, but Possible
3.
Outdoor Load Center (Panelboard)
An outdoor-rated load center is possible, but less likely to be used solely as a service disconnect.
Why it's less likely
Usually, you have a separate service disconnect before a panelboard. Using a panelboard as a disconnect is not always compliant.
What to look for
Larger Size
Load centers tend to be larger than simple disconnect switches.
Multiple Breakers
The enclosure would have a row or rows of individual circuit breakers visible (or a place where you could see the breaker positions) under a cover.
Dead Front Cover
A cover that protects access to the energized components when the door is open.
Rating Plate
A rating plate showing the total amperage rating of the panelboard and the maximum number of circuits.
Why it's unlikely to be something else
Given the 200A service, it is unlikely that a meter-main is in use as it would include a meter socket. A safety disconnect is often installed separately after the meter socket. Given the information that this is on the outside of the building in view of google street view, it is unlikely this is a sub panel.
In summary
Without seeing the photo, the most likely answer is that it is an enclosed disconnect switch. The second most likely is an enclosed breaker. Less likely is that it is a full-sized load center or a meter-main. If you can provide a link to the photo, I can offer a more confident assessment.
