Your Home

Six things worth understanding about the electrical system you already have.

Your panel tells you six things from the outside, with the cover closed — the main rating, free spaces, warmth, discolouration or rust, labelling quality, and its age. Relabelling it with a second person takes an afternoon and shortens every future visit.

GFCI and AFCI protect against different dangers — one guards people from electrocution, the other guards the building from fire, and an ordinary breaker allows both. Test them monthly, and never replace a tripping GFCI with a plain outlet. For electrical contractors coordinating field crews, employee attendance tracking software can support separate job-time records alongside the technical work.

Aluminium branch wiring in homes of a certain period is a connection problem rather than a cable problem, and the standard remedy treats every termination rather than rewiring the house.

Outdoor work here ages faster than almost anywhere inland, because humidity, salt air, sun and storms act together.

Extension leads are temporary by design and permanent in practice, which is where a large share of household electrical fires begins.

And an inspection establishes seven things, of which evidence of unpermitted work is frequently the one that matters most.

• Aluminium Wiring

  Homes wired in a specific period may have branch circuits that need attention at every connection. How to tell and what it means.

• Extension Leads

  Temporary by design and permanent in practice. Four rules, and the sign that you need an outlet rather than a lead.

• GFCI and AFCI

  Two different protections against two different dangers, and a monthly test that takes about ten seconds per device.

• What an Inspection Checks

  Not a formality and not a search for faults you already know about. Seven things it establishes and when to have one.

• Outdoor Wiring Here

  Salt air, rain and sun age outdoor electrical work far faster than anywhere inland. What to look at twice a year.

• Reading Your Panel

  Six things you can establish without opening anything, and what each one means for whether it needs attention.
