Why move to NFT?
A) Smaller Box Size -
If Customer does not need Sub-feed
space or does not want to pay for it.
• 6” shorter Enclosure than FT
• No Sub-Feed Space - pay for what you need only.
B) More Circuits needed -
If Customer does not need Sub-feed
space or does not want to pay for it.
• 12 more circuits than FT in same box size
• No Sub-Feed Space- pay for what you need only.
New Options to Consider!
1) If a Customer has an existing 42 circuit FT
installed and needs additional circuits, the
interior can be replaced by a 54 circuit NFT.
Re-use the same Enclosure and front.
2) If a Customer needs more than 42
circuits, you can use a 54 or 66 circuit
device and eliminate the second cabinet.
