heater electrical sparking?

[Steven Longstan]

Hi chaps,

ive had a call out to an electrical curtain type heater which the client said is sparking.

Upon inspection i cant find anything apartarnt.

However ive noticed that the isolator used on this signal phase supply is a TPN isolator. Ive recommended they change this to a DP isolator. Is they any way possible this could cause the spark?

im thinking no but i cant seem to find anything else it could be.

It's only a device for breaking 4 poles

Why may I ask?

 

[Steven Longstan]

well the tpn is 3 pole and the way it wired with the neutral it like on a single pole gets isolated were as it should be a double pole isolation.

just trying to rule out if this could be anything to do with the sparks.

To waste some money ?

well i thought the whole point in having an isolator in a single phase supply was to isolate both poles not just the one?

 

[Leesparkykent]

If you want to Achieve double pole isolation why don't you use one of the poles for the neutral?

too sensible.

yeah i suppose so.

however back to the original question. the fact the neutral is continues and not part of the isolator should not make a blind bit of difference and therefore shouldnt have anything to do with this reported sparking should it?

 

[telectrix]

no it should not.

 

[Steven Longstan]

no it should not.

exactly what i thought.

has anyone else ever had any issues with these curtain heaters doing this?

Using my extensive Sherlock Holmes experience "was this sparking occurring only at night Dr Watson" lol

 

[Steven Longstan]

no during the day after it had been on for about 2 hours.

Im thinking the client is possibly over reacting with the sparking and think it was more like a spark as she said it has happened a couple of times over past couple weeks. just one slight spark that caught the corner of their eye

i dont want to write the heater off and quote to replace it if something of nothink

Pardon

 

[telectrix]

probably a slight arc on the thermostat contacts as it switches in and out.

 

[Steven Longstan]

this is what im thinking it just the element doing a slight spark.

Is this deemed reasonably safe if it just this

pain in the %$&* thow when you got to drive 40 miles to attend site

 

[telectrix]

any rate, the heater should not be sparking unless it's qualified. has it got 2365, NVQ, etc.?

Or the innocuous Part P qualification

 

[Steven Longstan]

what do you mean has it got?
