with-in sight

[Shockedby277v]

We're building apartments with heat pumps in each unit. Instead of installing disconnects at each HP we're moving the panels so they are with-in 50' and in sight of the HP. In one apartment, you can see the HP from the panel but if you were standing at the HP you can't see the panel. I read the definition in Article 100. Now when they say "equipment", are they talking about both the panel and HP???

Yes

you can see the HP from the panel but if you were standing at the HP you can't see the panel.

Please correct me if I have missed something.
The disconnect means would need to be within sight of the motor controller of the HP, not the other way around, unless it is over 1/8hp, then a lockoff will do.

Rule of thumb, an A/C or Heat Pump has about One Horse Power per Ton of Refrigeration. Also, 2 Tons is about the smallest A/C that is not window unit. So, the HP would be more than 1/8 horse. What I can't understand is, there are some "value" priced non fused disconnects that would make things a lot easier.

Non fused disconnects $9. code compliance priceless.

I like your handle. And if a disconnect is not used, someone could be Shockedby240v

Re: with-in sight

Price is not the issue... appearance is. With the understanding electrical is suppose to be done correctly first ... appearance second... We're trying to avoid mounting a ugly disconnect in a living space. The panel could be moved. What throttle said is more of an answer I was looking for but he sounds unsure?.?.?.

Thnx for your replies.

I get it now, you have a motel type "though-the-wall" unit.

If that is what you have, then those units are serviced from the front, by sliding the unit forward out of the frame. Try 440.63

Thnx! Doh! The place is sealed tight and we're in the wrong.

Re: with-in sight

When you stated HP in each unit, I was thinking of the airhandler unit as what you were referring to. I wasn't sure though. I would not have guessed in was a "in wall" unit. Sorry.

If it is not an attachment plug assembly, you should still be able to use the overcurrent protection device if in a readily accessible location within sight of the unit.

440-65 would not apply if there is not a factory installed attachment plug.

Seen many without one? Not saying, just asking. I have never seen a PTAC without an attachment cord, unless it had a factory disconnect inside it.

Re: with-in sight

I have, but it has been more than 10 years ago, I paid no attention to if it had a disconnect inside as I was helping to get the jobsite caught up.(Hanging fixtures down the line

The statement about 440-65 was about the built in LCDI or AFCI requirements.
