Installation notes

Before you install.

Open a question for model-specific guidance and sources.

Verified against the manufacturer's documentation (rev. Manufacturer product specifications), checked 2026-10-19. Manufacturer documentation →

Which breaker is this?

Blue Sea 7294: Two-pole, 16 A magnetic-hydraulic breaker rated for 120/240 V AC. This catalog symbol represents its AC application. It has no residual-current protection.

How are the conductors connected?

The symbol keeps LINE L and LOAD L on one pole, and LINE N and LOAD N on the other. Both open together. Protective earth bypasses the breaker continuously; it has no PE terminal. The example assumes a protected supply and does not specify a complete main, branch or leakage-protection installation.

What does Crimp simulate?

Select On, Off or Tripped to change the contacts manually. Crimp does not calculate AC fault currents, automatic trip times, leakage detection or protection coordination. The connection overview has no calculated cable or fuse recommendation. Check the complete installation against the manufacturer's instructions.

Technical reference

Specifications and terminal map.

Check the model, ratings and connection points against your own unit before choosing installation hardware.

Catalog specification

A-Series 16 A magnetic-hydraulic AC circuit breaker, two poles, rated for 120/240 V AC. These AC breakers provide overcurrent protection without RCD/ELCI leakage protection. This symbol represents the AC application with separate line and neutral contacts; protective earth bypasses it. Crimp models manual contact states, not automatic tripping or AC protection coordination.

The map identifies line, neutral and protective-earth connections. This page does not calculate an AC cable size or protection rating.

Sources and connection guidance

Equipment specifications. Model details, ratings and terminal roles come from the catalog. Check your unit’s label and current manufacturer documentation for its exact revision.

AC planning boundary. The drawing identifies conductors and connection points; supported switching states show contact continuity only. Crimp does not calculate AC load flow or verify fault protection, leakage trips, source isolation or grounding. This overview does not calculate cable sizes or validate protective devices. Follow the complete manufacturer installation instructions.
