I have been asked to install a 0.5 KVA transformer with a 480/240 primary and 240/120 secondary.
A small, ground level sign with 3 recessed, incandescent fixtures (120 volt) was installed, along with the HID parking lot lighting (240 volt) for a new shop/office.
The lighting conduits include stubs to feed the sign. It would be much more labor-intensive to run a new 120 volt ckt. than to install this xfmr. and have the sign come on with the lot lights.
Assuming proper fusing and disconecting means, is this an acceptable plan?
