Greetings Topsy
Please what sequence do you suggest?

should be thunder arrestor and flat metal tape be installed during roofing?

If yes, could the tape running down to the earth be stopped at the block level to be rejoined later (to avoid theft before full earthing)

MUst earthing be done before final electrical installations?

Lastly are their fake and inferior arrestors and earth rods so that one can avoid them and buy originals?

should be thunder arrestor and flat metal tape be installed during roofing?
Ans: Yes the Thunder arrestor should be installed during the roofing to avoid leakage.

If yes, could the tape running down to the earth be stopped at the block level to be rejoined later (to avoid theft before full earthing)

Ans: The tape can be stopped at the block level and joined later to complete the earthing to ground using earth joint


MUst earthing be done before final electrical installations?

Ans: It Can be done during the cabling stage so that cable from EARTH PIT can be connected to Earth Bar/Distribution Board. Note that Earthing must be done on or before final electrical installations.

Lastly are their fake and inferior arrestors and earth rods so that one can avoid them and buy originals?

Ans: We have a lot of fake Lightning and Earth rod, If you are not familiar with the materials you will hardly differentiate the fake from the original.

NOTE: Separate the lightning arrestor from the normal earthing.

Thanks

ok, if its the chinko knife change over , then go for 200amps,its about 5k naira, while 100amp is abt 3500 naira or so..not much difference.

but if its the bulky clunky types that make a sharp loud sound when engaged, you are ok with the 63amp type

With the type of load he has a single phase change over switch is not advisable. The knife change over switch comes in single phase and not THREE phase.

Nice weekend

earthrealm:
theoritically, a 2hp ac is abt 1600w / 240v = 7amps approx, yet 15amps fuse is specified for it, water heater, small ones is 1000w, big ones 1500w, 1000w/240v = 4amps approx, so 11amps total for 1 room, using a 20amps fuse/breaker ix an acceptable design philosophy.
again, the market is awash with fakes, a 25amp rated product might actualy be 10amps! in reality
the op is asking about changeover abi??...for nepa/generator??

Well, you are right but the reason of using 20A to protect the AC is because of the starting current. Starting current is 2xtimes the running current. Running current of AC is about 9.1A , Below are some wattage of equipment

AC 2000W
water heater to be 1500W

sako28:
8 nos of 1hp AC.
1 no of 1.5hp AC.
4 no of 15 liter water heater.

Base in my calculation, the total load up s 81A I have factor all other things like cooker and also assumed that you are using LED light.

So better to go for 100A TPN changeover switch.

earthrealm:
not advisable, though its load dependent, assuming 1 ac+1 hot water tank per room, thats about 20amps x 5, then sitting rms and all. i recommend 200amps or even higher, such items are not that expensive, its better you buy higher capacity that lower wch will overheat, burn when overloaded

200Amps is much and besides 20Amp is not really for AC. There is calculation that normally determine the total load of a particular building

sako28:
My Ogas,
Can a 63A changeover switch carry a 5 bedroom duplex.

Thanks
Sako28

How many AC, Water heater do you have? I can do my calculation and get back to you

Reprobate:
IS THIS QUOTE FAIR FOR THIS TYPE OF BUILDING, AM TRRYING TO HELP SOMEONE INVESTIGATE. its a 6br bungalow

2NDLY, THE ROOFING SHEET, 'what type of material does it look like?
what do you think is the estimated cost?

It depends on the taste of client. The materials listed in the quote is too small for the FULL conduit and using 12-ways DB single phase MEM for the total number of equipment to be installed, i doubt it.

Price of cable is low

Dageek:
I have been a silent follower on this thread. And I must say the truth, I have gain a lot of things from professionals here.

I started my building project last year Nov 7 and today made it a year. I am really happy it has got to finishes stages.

I will post pictures of the building later, but I would need the help of the professionals here to help me out on the cost of this things :

I have done the electrical piping, the plumbing piping, so am about installing a POP and SUSPENDED CEILING

I have called someone from my hood here and he gave a quotation of N268,000 for a measurement of 67sqm. (Workmanship inclusive)

I have asked for the break down of the cost, so I can get the cost for materials and the cost of workmanship.

but while waiting for his answer, I want to know how POP ceiling are prices per meter.

POP per square meter should be between 3000 - 3500naira per square meter. But remember your electrician must pull the cables before the commencement of POP/sespended ceiling

Thanks
