Installing Surface Mount Fused Disconnect Next to Flush Mount Panel

[CJARNUTOWSKI]

Hi Guys

This question pertains to an indoor residential application (garage). Washington state, USA.

I would like to install a surface mount, 240v fused disconnect adjacent to (within 10ft) a flush mounted 200A panelboard. The panelboard bus is full, so I will be feeding the disconnect from the feed-through lugs. Tap rules require that conductors be enclosed in a raceway (240.21). A 240v surface mounted receptacle will be wired in EMT to the disconnect.

I'm looking for some advice. Can I run the feeders to the disconnect in steel flex from the side of the panel to the back of the disconnect, all behind drywall? Does the sheath on SER cable count as a raceway? Maybe there is a cleaner way to do this that I'm not thinking of.

Thank You!

If I were able, I'd feed another small loadcenter off of the feed thru lugs of the existing panel with full size conductors and forget the tap.

Can't install a couple of tandems on small circuits to make room for a new 2p breaker? What is the new load type and size?

Unfortunately no. Panel already has tandems installed where possible. The intended load is a 30A inverter welder, and perhaps a drill press in the future, though not used concurrently.

If I were able, I'd feed another small loadcenter off of the feed thru lugs of the existing panel with full size conductors and forget the tap.

Anything that is fed by the feed thru lugs would have to fall under tap rules unless I use 200A wire.

There is nothing wrong with using the feed through lugs and applying the appropriate tap rule. If it were me I would install a new panel with a main fed from the lugs.

unless I use 200A wire.

Which is exactly what I woiuld do.
No use choking the feed thru lugs down to a single circuit when you could install the panel and allow for a few extra circuits which sounds like is long overdue.
