New multimeter, suggestions?
The Brymen BM869s is a truly great meter at an extremely good price. CAT IV / 600v CAT III / 1000v, 50,000 counts, 100Khz bandwidth. It's almost impossible to find another meter with similar specifications at even half again the price. This one actually betters a Fluke 87V on specs. Telonic is...- rs1987

Undersized low voltage transformer?
Absolutely agreed. I've just got to convince the landlord as I cannot change it without his permission. This gives me good reason to advocate for the change.- rs1987

Allowable electrical work by non-registered person
In terms of the Part P regulations, am I as a DIYer (that is to say non-registered electrician), allowed to replace the dimmer module in a light switch myself and replace the transformer on low voltage lighting with a new one? I will not be installing any new equipment and neither will I be...- rs1987

Undersized low voltage transformer?
I hooked up a DC voltage supply instead of the AC one to get around the limitations of my multimeter. At an output voltage of 12.5v DC, some of the bulbs draw 0.8A of current and others draw 1.6A of current. The readings are repeatable in an accurate manner. They seem to be a mix of 10w and...- rs1987

Undersized low voltage transformer?
The problem is that these bulbs do not have any markings on them whatsoever, so unless I measure their current draw then I'm in the dark about their actual wattage. I plan to convert to LED anyway, but since I need to replace the dimmer modules at the same time, I need to get the landlord's...- rs1987

Undersized low voltage transformer?
Thanks all for the helpful replies. Since I'm 100% sure that all six bulbs are connected to the transformer, I suspect possibly my multimeter might be faulty and that the load is not as high as double the transformer rating. I'll get hold of another multimeter and check the current draw on the...- rs1987

Undersized low voltage transformer?
Possibly yes. However, the immediate question is a safety one. I assume that if left on for a period of time this could lead to the transformer heating up substantially and being a fire hazard, right?- rs1987

Undersized low voltage transformer?
Yes. All 6 are being fed from the single transformer. The spec sheet for the transformer does say that it has overload protection tested at double the load. Which seems to imply that the overload protection will only trip off if exceeding double load, but it's not entirely clear from the spec...- rs1987

Undersized low voltage transformer?
I've just moved into a place that has low voltage halogen lights in the kitchen. I had a look at the installation and I see they are running 6x20w G4 halogens off a single DA-E60 transformer - specifications for the transformer shown below. I measured the amperage draw of the light bulb at 1.8A...- rs1987
