With such items as instant hot water heaters booming in the market place the industry needs to produce a reasonably priced disconnecting means.
I'd favor some wild variant of the A/C disconnect. You know... The one that is as simple as can be -- a variant of a fuse holder.

I think I posted a question about this problem before. I came across those instant hot water heaters that Tesla is talking about. In my case there was a sub panel right next to the heater and there was three 2 pole breakers for the unit. The EC marked the panel and the heater very clearly stating that there is more than 1 feed to the piece of equipment. Also the sub panel was in reach of the heater and all breaker were also marked.

If you have a local sub panel, why not just get one with a main breaker and label it as the disconnect?

That is because the EC will have to buy a service panel with main breaker and the homeowner wants the job done for less! Or else the other EC will bid only a sub panel with 3 breakers instead of main panel and 4 breakers.

I was thinking more like an 8 slot panel with a back fed main.
They are not that expensive and we still need to have a code complying installation, no matter what.
