what price?

[hornby]

Have to go and inspect some faulty wall mounted panel heaters.

I will be charging per hour, so guys what is the usual rate as i dont really do work for myself.

It will be for a busy commercial office in the center of town.


Regards, Marcus.

 

[i=p/u]

some say they £25 per hour, if u have van , tools, testers, insurance and all that stuff

 

[Marvo]

It seems to vary from area to area. Did you check out this thread?

 

[sparx24]

£30/hr domestic, £35-40 commercial/industrial, plus tax.
Very rural area.
Take it or leave it, most take it, local reputation & registration with Trading Standards/Trustmark helps.

Cheers guys checked out the job. Anyhow x3 (3KW Dimplex heaters) were installed on a 2.5 T&E, covered by a 20A Type B MCB. Circuit even had an inter connection. One cable going off to feed 2 heaters and 1 going off the other way for the other one. So I am going to suggest re-wiring properly as a radial using 4mm T&E and sticking in a 40A MCB. Their are no spare ways in the board so seems the only choice rather than seperate circuits for each heater. 9000watt comes to 39A so that protective device will cover it, although I am wondering should it be an RCBO these days in commercial office blocks supplying fixed equipment or can I get away with a MCB and what type usually for these heaters B or C? Would you believe I had my 17th

You cant use 4mm and a 40amp breaker.

 

[J@mes]

6mm, 40A type B and I'm not sure on the RCBO without looking at the BRB, which I cannot be ***** to get off the sofa for!

One cable going off to feed 2 heaters and 1 going off the other way for the other one. So I am going to suggest re-wiring properly as a radial using 4mm T&E and sticking in a 40A MCB.As previously stated a 40a mcb will exceed the rating of a 4.0mm T/E Their are no spare ways in the board so seems the only choice rather than seperate circuits for each heater. 9000watt comes to 39A so that protective device will cover it,You will need to calculate volt drop and select a cable accordingly although I am wondering should it be an RCBO these days in commercial office blocks supplying fixed equipment or can I get away with a MCB and what type usually for these heaters B or C?As long as not socket outlets,buried cables or a TT no requirement for RCD....no inrush current so a type B would cover, Would you believe I had my 17th ....Hmmm.....

I've got a job coming up shortly installing a few 3kw dimplex heaters, the ones i'm putting in are those quartz ones though, the tech specs say use type c. Just thought i'd mention it, worth checking on the dimplex site for any info you need if you haven't already.

i also wouldnt fuse a 3kw heater at 40A, and your not goin to be able to terminate 6 or 10mm in the back of a fcu so new cu it is, y not put a 40a in the spare way and feed a new db suppling 3x16a radials ? also if its in an office ur not goin to need rcd protection. sorry im goin to say shouldnt but u should know the req for rcd aswell as i do so il leave that down to your discretion

 

[egginyourface]

oh oh....here come the rcd brigade...

 

[hornby]

cheers for help guys, just recently came out my time working for big companies and as you know you always get a db schedule to walk you to the finish line with everything already calculated so just starting to think outside the box. I'm most likely correcting an older persons work here, im still preety young, but thanks again. Using a 6mm would be a struggle to terminate but manageable, although i like the idea of an additional db, i shall pass both ideas onto the client. regards Marcus

Many many factors we do not know that would decide whether he needs to rcd protect it...

Is your thoughts that it is fixed equipment in an enviroment of trained/skilled people, which in an office is unlikely.

 

[ridemx27]

what regulation states that fixed equipment unless in an Environment of trained/ skilled must be rcd protected ? are u trying to refer to 411.3.3 which is for SOCKET OUTLETS! and is under supervision of skilled or instructed persons? I was also persuming that earthing was present and compliant, circuits will more than likeley be run in surface trunking and obtain a zs reading that meets req for disconnection time of 0.4s, he also stated he is 17th edition which is y i put my comment in the last post about knowing requirments for rcd protection, anyway it was only a suggestion i made which may or may not of been a good idea but thats how i would prob do it.

I do appoligise to hornby here after reading back i worded completly wrong and sounded rude and dont have an attitude in the slightest im only on here to help where i can and gain help when needed hence the edit sorry mate what i was trying to say bout knowing the requirements is because i dont wanna tell you simply not to rcd protect something and be wrong as i can only guess most of the key factors.... but at the same time i dont want to insult you as i dont know your experience/ knowledge etc, i learnt by asking i still learn by asking and im always happy to help if i can ok

 

[mogga]

17th but please dont ask me to quote correctly the BRB thats where some guys need guidance As once you have finished your apprentice ship is when you realy start learning with noone to hold your hand hence its better to ask a stoopid ( seemingly0 question than bungle on n make a silly(potentioaly lethal) mistake
