Re: [Elecraft] How far can the KPA1500 amp be from the PS?

Ted, I wonder if the load center panel is mounted on an exterior wall? If so running a penetration from the panel to outside might be better. Then you could route it in conduit or exterior cable routed along exterior to a good spot to bring it back inside at the lower level. That still

Re: [Elecraft] How far can the KPA1500 amp be from the PS?

At the risk of spinning this off topic, I am reminded of the lesson I learned years ago when I drilled a through hole through the foundation for our low voltage walkway wiring. I wondered at the efficacy of my brand new shiny Dewalt hammer drill because it was taking me freaking hours to go a few

Re: [Elecraft] How far can the KPA1500 amp be from the PS?

Ted, The routing of the 240 volt wiring is a discussion between you and the electrician - but there is always "a way" - even if that means drilling through concrete (not nice, but possible). Unless the wiring route is short, take Jim Beown's (K9YC) advice about conductor sizes. Large

Re: [Elecraft] How far can the KPA1500 amp be from the PS?

Ed, I live in a 4 level split. Not a good situation for my knees and running power lines. I assume the breaker box is on an outside wall. Here is what I did . I went outside. My shack in on level three, half buried in soil. Ground level comes up to just below the windows. I had an electrician

Re: [Elecraft] How far can the KPA1500 amp be from the PS?

Placing both PS and amp where the 220 VAC outlet is accessible is possible; but then I wouldn't be able to see the amp while operating, which I would like to do. Wouldn't feel comfortable with a 1500 watt amp running way out of sight. It would also then be in the kitchen on a floor above.

Re: [Elecraft] How far can the KPA1500 amp be from the PS?

I concur...  Should have replied to the original post.  Sorry. OK...  you NEED 240 in the shack, so if you are going to do it... and you should, do it right. Put a sub-panel in the basement and take at least a 60, preferably an 80+ Amp line from the main box to the sub-panel.  Then hack out

Re: [Elecraft] How far can the KPA1500 amp be from the PS?

Ted, I would opt for bring the 220 line into the shack. Ask your electrician about using a receptacle mounted flush on the floor. You have likely seen them used in commercial buildings - conference rooms and other places - the cover plate is usually brass with a "door" to expose the

Re: [Elecraft] How far can the KPA1500 amp be from the PS?

Why not just use the amp as-is near the 220V outlet and run longer RF coax cables to the amp from your operating position? Dave AD6A Sent from my  iPhone X On Apr 28, 2018, at 6:54 AM, Dauer, Edward wrote: The KPA1500 Manual states that “the power supply can be operated

[Elecraft] How far can the KPA1500 amp be from the PS?

I would revisit running a 240 outlet into the shack. You would need very large conductors to have the power supply that far away and laying these wires on the floor would certainly not be aesthetically pleasing. It is sometimes a bit of work and may require some drywall repair however I cannot

[Elecraft] How far can the KPA1500 amp be from the PS?

The KPA1500 Manual states that “the power supply can be operated remotely” and that the supplied cables are 66 inches long. It does not say how far apart, beyond the 66 inches, the PS and the amp can be without affecting performance or creating other issues. Does anyone know? There are
