Electrical Wire Caps & Screw Terminals (P1, P2, P3, P6) – Complete Guide
These connectors provide quick, secure, and reusable wire connections without crimping or soldering. They are widely used in electrical panels, lighting, appliances, and DIY projects.
???? Types of Wire Caps & Screw Terminals
1️⃣ Push-In Wire Connectors (P1, P2, P3, P6)
Spring-loaded – No tools needed, just insert stripped wires.
Reusable – Some allow wire release with a lever.
Common Sizes:
P1 (~1-2 wires, 0.5–1.5mm² / 24–16 AWG)
P2 (~2-4 wires, 1–2.5mm² / 18–14 AWG)
P3 (~3-5 wires, 1.5–4mm² / 16–12 AWG)
P6 (~6 wires, 4–6mm² / 10–12 AWG)
✅ Best for: Fast connections in tight spaces (e.g., junction boxes, LED strips).
2️⃣ Screw Terminal Blocks
Clamps wires with screws – More secure for high-current applications.
Types:
Barrier strips (for panels).
Euro-style DIN rail terminals (industrial use).
Mini screw terminals (PCB/electronics).
✅ Best for: Permanent installations (e.g., circuit breakers, transformers).
???? How to Use Push-In & Screw Terminals?
Push-In Connectors (P1-P6)
Strip wire (~8–10mm).
Insert into hole (no twisting needed).
Tug gently to ensure a secure grip.
To remove (if reusable), press the lever (if available) and pull.
Screw Terminals
Loosen screw.
Insert stripped wire.
Tighten screw (don’t over-torque).
Check for loose strands.
⚠ Warning:
Avoid stranded wire in push-ins (unless rated for it).
Don’t mix wire sizes in one terminal.
???? Pros & Cons
| Type | ✅ Pros | ❌ Cons |
|---|---|---|
| Push-In (P1-P6) | Fast, no tools needed | Not ideal for high vibration |
| Screw Terminals | Secure, reusable | Slower, needs screwdriver |
???? Common Applications
Home wiring (light switches, outlets).
Industrial control panels.
Automotive & marine wiring.
LED lighting & solar installations.
???? Where to Buy?
Push-In (Wago, IDEAL, LeGrand) – Amazon, electrical suppliers.
Screw Terminals (Phoenix Contact, Weidmüller) – Automation stores.
???? FAQ
❓ Can I reuse push-in connectors?
→ Some can (lever-release types), but most are one-time use.
❓ Which is better: push-in or screw terminals?
→ Push-ins for speed, screw terminals for high-current/vibration.
❓ Can I use solid and stranded wire together?
→ Only if the terminal allows it (check specs).
