Hi Everyone,
We have a house which when built , had plans for future expansion.
They left in the walls a wire from the panel (not connected!) to the
outside when the addition would go.We wanted to know what this wire
could be used for, or is it big enough to feed a subpanel for the
planned expansion?

The wire is marked : essex 4-4-4 type se ?HHW

I know an electrician would be able to help but I hate to bother them
with what should be a simple question, and most contractors round here
would much rather trench a new feed or tear up our walls to get a
feed....So.. How many amps could it feed ?.

Amny help very much appreciated

If it just listed the three numbers, it would indicate only three
conductors, so it probably wasn't for a sub panel, at least a 120/240 volt
sub panel. It could have been for an air-conditioning condenser unit or heat
pump

Some kind of BODACIOUS heat pump there with 100a service.

What 100 amps, it's only good for 65

Hi everyone,
Sorry to resurect an old thread, but I had to relate this.
We had an electrician out. He told us this wire was likely for a
planned addition and this would be for a feeder to the addition's sub
panel. Confused, I said to him "but we have only 3 conductors, and no
ground?" To this he replied:

"It is common practice to ground the sub panel AT the subpanel, there
is no need to run a ground from the main breaker box. This also saves
copper."

So ... Is this indeed common practice/code?

Not grounding to the originating panel is only permitted for a separate
building (like a garage). And probably won't be allowed for separate
buildings in the 2008 NEC.
