3M 7000133321 – Frequently Asked Questions
1) What wire sizes do 3M Scotchlok MV14 fork terminals take?
The Scotchlok MV14 vinyl insulated fork terminals are sized for 16 to 14 AWG stranded copper (1.31 to 2.08 mm2). The barrel inside diameter is 0.090 inch, and the insulation funnel accepts wire with an outer diameter up to 0.145 inch. Anything heavier than 14 AWG needs a larger terminal.
2) What is the difference between the MV14-8FX and MV14-10FX fork terminals?
Both are the same 16 to 14 AWG blue vinyl insulated fork terminal; the difference is stud size. The MV14-8FX (MPN 7000133320) is for a #8 stud and the MV14-10FX (MPN 7000133321) is for a #10 stud. Match the number to the screw or terminal-block stud you are landing on.
3) Is the 3M Scotchlok MV14 fork terminal rated for 600V building wire?
Yes, 600V for building wire, and 3M rates it to 1000V for signs, fixtures and luminaires. The catalogued maximum recommended voltage rating is 600 V. It also carries UL file number E23438.
4) Can I use a fork terminal instead of a ring terminal on a free-standing stud?
That is exactly what this one is for. The MV14 fork has a wider tongue intended for free-standing studs, so it slips under a loosened screw without removing it, which is the advantage over a ring terminal. Use a ring terminal instead where vibration or a code requirement calls for a connection that cannot back off the stud.
5) What temperature range can these vinyl insulated fork terminals handle?
Minus 40 to 221 degrees F (minus 40 to 105 degrees C). That covers unconditioned mechanical rooms, rooftop equipment and outdoor sign cabinets. For anything running hotter than 105 C at the terminal, move to a nylon or high-temp insulated terminal.
6) What are these Scotchlok terminals made of, and are they RoHS compliant?
The barrel is ETP electrolytic copper with a brazed seam, sleeved in blue vinyl (PVC). They are RoHS 2011/65/EU compliant without exemption, and manufactured in the United States, which matters on Buy American and federal jobs.
7) Will the vinyl sleeve slide over 14 AWG THHN insulation?
The funnel-entry PVC sleeve on the MV14 is dimensioned for insulation up to 0.17 in (3.7 mm) outer diameter, with a maximum insulation OD of 0.145 in at the barrel. Standard 14 AWG building wire falls inside that. Heavily jacketed or double-insulated conductors can exceed it.
8) How many fork terminals come in a bottle, and how many bottles per case?
Each bottle holds 100 terminals, and a case is 500 pieces. The bottle packaging suits a service van or a shop bench; the case quantity is the buy for a panel-build or a fixture retrofit across a property.
