Practical limits

Use this as a load check only.

FRZ cannot inspect hidden wiring, damaged sockets, RCD behaviour, moisture inside equipment, cable condition or local site rules. It helps you spot obvious load and cable problems before temporary kit is used.

Do not push through red flags

Heat damage, burning smells, wet electrics, damaged plugs, repeated tripping or unknown cable ratings are reasons to stop and get help.

The real site matters

Commercial sites, old installations, wet rooms, workshops and critical rooms need more care than a web calculator can provide.
