buzzin

[bahco]

right lads need your help please

ive fitted some lv downlights and a lv fitting in my lounge, took the pendant off into a jb then to the 4 spots and the lv fitting, power on all working fine

then walks past my consumer unit and i can hear a buzzin hummin sound, so i take the lid of listen a bit closer went into the room were i fitted the lights turned them off and the buzzin stops.

now the lv light fitting which i replaced the pendant with had a tranny built in but it was non dimmable, so i replaced it with a osram one

you think it could be the transformer? and also ive replaced the 1g switch with a dimmer, its a 400w dimmer easy enough to take the load but that is makin a slight buzzin sound.

the lighting circuit is on a 6a mcb which powers 4 rooms approx 500 watts which i make round about 3a

getting a bit paranoid now so any help would be great thanks matt

might sound simple but have you tried tightning up the cb half a turn sounds like its not tight enough. worth a try

check connections are tight
if it continues to buzz it may be worth while to replace it ,if it has tripped previously through short or overload it could be worn
alternativly take it out ,bang it on the desk a few times put it back see if it that cures it!!!!!
