Can you extend the location of a transfer switch away from the panel box?

So I’m putting in a transfer switch for my parents home, a 50 amp manual switch just to run the essentials during an outage. My dad has a hard time getting up and down the stairs to the basement, think more of a celler basement, low ceiling and uneven floor. My question is would it be ok to “extend” the wires via conduit to the top of the stairs, so he could just open the door and turn the switch from there? Roughly 25’ from panel. Thanks in advance for any help!

You can put it anywhere, the only limitation would be manufacturers instructions.

Is the transfer switch service rated? In other words, is it right after the meter or between the main disconnect and another panel.

As long as the normal power conductors are on the load side of the service OCPD, they would be feeders and not subject to any length restrictions. If the normal power conductors are service conductors, that would be a violation.

Yeah it’s just a small 5 circuit transfer switch. You take 5 circuits from the main panel box that you want on emergency back up, and spice them into the manual switch wires, then the switch legs from the transfer switch goes back into the circuit breakers in the main panel. So you can manually flip from normal operation to generator. Just going to run a few for lights, fridge, and the furnace blower motor.
