F4P P 9901 – Frequently Asked Questions

1) What wire gauge ranges do F4P P-Series twist-on wire connectors cover?
The P-Series covers six ranges across its models: 14-10 AWG, 18-10 AWG, 18-8 AWG, 22-10 AWG, 22-14 AWG, and 22-8 AWG. So the family spans 22 AWG low-voltage conductors up to 8 AWG feeders, but no single connector covers all of it. Pick the range that brackets the combination you are actually splicing, not the widest one on the list.
2) Which color F4P wire connector do I need for 8 AWG wire?
Two of the P-Series options reach 8 AWG: the tan connector, rated 22-8 AWG, and the red connector, rated 18-8 AWG. If the splice includes anything smaller than 18 AWG alongside the heavy conductor, go with tan. The red 18-8 is the one to use when every conductor in the bundle is 18 AWG or larger.
3) Are these connectors rated for aluminum wire?
No. F4P P-Series connectors are built for copper conductors only, with copper contact material and a copper-rated wire range. Aluminum and copper-to-aluminum splices require a connector specifically listed for aluminum, typically with an anti-oxidant compound inside. Do not substitute these for that job.
4) What is the difference between the two yellow F4P connectors?
There are two yellow P-Series options and they are not the same range. One is 18-10 AWG, the other 22-10 AWG. The 22-10 accepts finer conductors in the bundle, which matters on control, thermostat, or low-voltage runs mixed with branch wiring. Both top out at 10 AWG. Same thing happens in red: an 18-8 and a 22-10 both ship in red, so order by the AWG range, not the color.
5) Will these twist-on connectors fit inside a shallow single-gang box?
Body size varies a lot across the P-Series, so it matters which model you order. The smallest, the P 3001, is 0.84 inches long and 0.33 inches in diameter, and the P 1101 is 0.94 by 0.27 inches. The largest, the P 1301, runs 1.21 inches long and 0.92 inches in diameter. For tight box fill, the P 3001 and P 1101 take up the least room; the P 1301 and P 9901 (0.795 inch diameter) need real space behind the device.
6) How many F4P P-Series connectors come in a bag?
These ship 500 to a bag, in a single color and wire range per bag. That is a job-box or MRO quantity rather than a handful for one device, so if a building needs several ranges on hand you are ordering a separate bag per range.
7) Which F4P connector should I use for 22 AWG thermostat or control wire?
Three ranges reach down to 22 AWG. Orange is 22-14 AWG, which is the tight one for small control and signal conductors on their own. Yellow 22-10 and red 22-10 handle 22 AWG mixed with heavier branch conductors, and tan 22-8 stretches furthest if a large wire is in the same splice. For pure low-voltage bundles the orange 22-14 grips best because the spring is sized for the smaller range.
8) Are twist-on wire connectors like these okay for equipment that vibrates?
Each P-Series connector uses an internal spring inside a shell, which is what holds the twisted conductors under tension and resists loosening from vibration. That makes them workable for motor, fan, and equipment whips as well as ordinary branch-circuit splices in residential, commercial, and industrial boxes.
