Wiring Never mind

[unky_gumbi]

So I am at the point that all I need for my grinder is the VFD. The wheels are on and lined up, the platen is square and attached, the issue now is power. I found out last night that the house had a fire in it well before I moved in and the wiring was all redone and that the house has a 100 amp service. I still need to crawl into the basement, its unfinished with a trap door entrance, and check if there panel to make sure there is room for a 230V/30 amp breaker.

Is there anything I should be looking for besides space in the panel? And how would I verify that the house is in fact 100 amp service? If I can do this it really makes my VFD choice and selection much easier because I could then just grab a Teco FM50 and be done with it

So I just got out of the basement and was quite happy with what I found. Aside from all the cobwebs I was able to confirm the 100amp service then I noticed this funny looking outlet down there with nothing plugged into it.

Turns out that the drier plug is just sitting there unused because the house has a 120V apartment size drier. There are 2 240V breakers, one for the stove (50 amp, bottom right of panel) and the drier outlet 30 amp top right of panel) so it looks like I am in business:thumbup: Now do I just run a long plug to the VFD or do I relocate the outlet to the room I will be working in. No there is no way I am moving the "shop" into the basement, lie I said it is a trap door to get down there and it is only 18"X18" it would be a real PITA to get tools down there and for me to climb in and out of it too

If the wiiring and panel is new, this should be easy.

And how would I verify that the house is in fact 100 amp service?

The panel will have one main breaker and then a sub panel with lots of little ones.
The big breaker will have the number 100 on it..



I s there anything I should be looking for besides space in the panel?

Take note of what type of panel it is.
Look for a trade name like federal and copy the model number down

You need 2 breaker spaces side by side so one side picks up one hot, and the other side picks up the other hot.

For wiring 220, you need 2 breaker spaces.
When you buy a new breaker, make sure it is the right one for that panel type.
Some screw in, some snap in, everybody has a diffrent system and you need to match it.

edited to add, I was typing while you were, nice simple.

Now do I just run a long plug to the VFD

or do I relocate the outlet to the room I will be working in.

I would relocate.

I would remove the outlet from that box.

copy the same wire (size and #, ther are newer plastic insulations)
make the connection inside that box and use a cover plate.

run wire to your location and add a box, put that outlet in it.

Get a dryer type plug and wire for your grinder.



Box,
cover plate
Wire
Marettes . wire nuts
steeples to nwil the wire down with.
plug and wire for your grinder
(one piece moulded units are available
I like to scrounge one on garbage day from ovens that get tossed..)
