Pauluk Are they particularly concerned about keeping them out of the sun or something?
Yep. We had the GANZ debacle here in Auckland [1988 - 1992]. Many thousands of cheap
GANZ GE 24 meters were installed, within a short period brake magnet assemblies distorted in the sunlight and caused the discs to start poleing on the magnet, hence slow running meters or completely stopped meters. Also it interferred with the jumping dials of the latter. These got stuck between 10's, 100's, 1000's or 10000's.
We had also a few problems with
GEC C11B2A meters which had the bottom bearing drop lower and poleing discs occurred. {cheap plastic assemblies) to hold floton bearings in place.
Electronic meters
Y120 Ep Enermet suffered from capacitors failing on the circuitboard.
In general the south side of the house is in NZ the coolest side and the meter is not exposed to the full sunshine which is quite intense in the summer.
The only meters with full metal geartrains still made are the
Email M3 meters from Australia, which are extremely reliable and rated for tropical conditions.
Also the PT coils have extra layering to deal with lightning strikes and powersurges.
