I have a contractor who wants to use a manual xfer switch as the service disconnect. Are there any issues with this? It is SUSE. It's not something we see done every day, so I'm asking for advice. This is for a new electrical service for a bank.
Must be "Service Rated" and Have the available Fault Current Rating.
Does it have a breaker or fuse?
Requires the overcurrent device to have an interrupting rating not less than the maximum available fault current.
Many Non-Fused disconnects can not be rated for higher Short Circuit current. (SCCR)
Hope this helps.
If the manual transfer equipment is listed as suitable for use as service equipment, and the installation meets the requirements of Article 230, then it can be done. NEC Article 702 would also permit the installation.
The only thing that has me in doubt is whether or not the power company has any specific requirement. Plus, I feel like I'm missing something.
Good point, check with the Utility and see if the manual transfer equipment is approved service equipment. Many utilities set their own requirements for transfer switch installations.
