Help: Can this Transformer Handle a 50 AMP Outlet?

05/21/2017 7:51 PM

Disclaimer: I'm not an electrician. I have an electrician who is doing a job for me and his mother in law passed away and he asked me to find out about this transformer. I have spent hours in the web trying to figure it out. What I need is an 50 amp outlet.

Here's what I have access to:

<a href="http://s397.photobucket.com/user/tander123/media/image1-2_1.jpg.html" target="_blank"><img src="http://i397.photobucket.com/albums/pp51/tander123/image1-2_1.jpg" border="0" alt=" photo image1-2_1.jpg"/></a>

Transformer panel:

Outlet on right of transformer:

None of the links are working for me....click on the camera icon in the posting window to link to photos....what is the 50 amp outlet for? what is the voltage? Why don't you just contact another electrician?

Yea, the location is embedded in the code (eg-http://i397.photobucket.com/albums/pp51/tander123/image1-2_1.jpg), don't know why it added the link to the photos but not the photos themselves.

I am assuming you want to add an additional 50A outlet to an existing building step-down transformer.

Unfortunately none of these photos gives any indication of transformer power or current capacity, I cannot even make out the fuse ratings.

You will need to talk with the electrician, he should really be assessing if the circuit and capacity is suitable for an additional 50A outlet.

Any transformer can handle a 50 amp outlet given an outlet does not draw any power.

It's what load you plug into it that will determine how well whatever transformer you chose will handle it, if at all.

What does the nameplate say as to voltages and amps? The wiring legend is not helpful.

The tan wire nut may be the best clue we have...

It is fundamentally wrong for an Electrician to ask <...not an electrician...> about technicalities that the Electrician should already understand as part of the trade. Doing so has the implication of transferring liabilities from Electrician to Client that would be inappropriate given the direction of the financial transaction between these parties. Therefore it would be very unwise, nay foolhardy, even, for the Client to supply an answer here.

If the <...access...> is available then the Electrician ought to be able to sort this out without bothering the Client, as that activity is exactly what the Client needs the be prepared to pay for.

There is no such thing as a <...50 AMP outlet...> in the UK for domestic use; a load of that size will present as a fixed wiring installation and not go via a plug-and-socket for domestic use. The need for a <...transformer...> in connection with it is completely meaningless here given the absence of any numerical information in the original post.

The data of <...mother in law passed away...>, though sad in itself, currently holds no relevance to technicalities that can be seen from here.

Sorry. The links aren't working. I think I have it figured out. I would delete the question but I can't quite figure it out on this forum.

I don't think deleting the thread is possible.

By "I think I have it figured out", does that mean you have your answer, or you have figured out how to make the links active?

I would say a 50 A breaker is not usually found in the USA (120 VAC), so it would certainly not be found typically in any domestic setting on 50 Hz, Europe for example.

Those houses are on 240 VAC, and 50 A on a system would be (single phase), roughly 12 kW, and that is too much power to be messing with in a domestically wired arrangement.

What are you really working on? Are you sure that was not a 15 A breaker?

50 amp and larger breakers are common in the US.

My electric stove uses a 60 amp double pole unit and I have numerous 100 amp circuits in my shop.

But those aren't in your house (the 100 amp ones). The electric stove, I get that now, and that is not on the normal voltage of 120 VAC, but is on 240 VAC dedicated circuit, right?

Standard 120/240 split single phase.

As for the house the only reason I don't have any 100 amp sub circuits is because I have no items that would require that amount of capacity.

Almost surely no.

That transformer looks like about 7.5 kVA (if much bigger then it wouldn't be wall-hung). For 240V output, 7500/240 = 31.25 A. For 120V output, you could theoretically get 62.5 A, but I know of no 120 V outlets even close to that high.
