ECN Forum Forums Code Related Discussion NEC & other Code issues Anyone know where to find the ibc 2010 elec ref?

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.
